Highlights of GAO-05-257, a report to the Subcommittee on Antitrust, 
Competition Policy and Consumer Rights, Committee on the Judiciary, 
U.S. Senate:

Why GAO Did This Study: 

Since its introduction in 1994, direct broadcast satellite (DBS) 
service has grown dramatically, and this service is now the principal 
competitor to cable television service. Although DBS service has 
traditionally been a rural service, passage of the Satellite Home 
Viewer Improvement Act of 1999 enhanced the competitiveness of DBS 
service in suburban and urban markets. GAO agreed to examine (1) how 
DBS subscribership changed since 2001; (2) how DBS penetration rates 
differ across urban, suburban, and rural areas; (3) how DBS penetration 
rates differ across markets based on the degree and type of competition 
provided by cable operators; and (4) the factors that appear to 
influence DBS penetration rates across cable franchise areas.

To complete this report, GAO prepared descriptive statistics and an 
econometric model using data from the Federal Communications 
Commission’s annual Cable Price Survey and the Satellite Broadcasting 
and Communications Association’s subscriber count database. 

What GAO Found: 

Since 2001, the number of households subscribing to DBS service has 
grown rapidly; thus the percentage of households subscribing to DBS 
service, the DBS penetration rate, has grown to over 17 percent of 
American households.

Aggregate DBS Subscription and DBS Penetration Rates, 2001-2004:

[See PDF for Image]

[End of Figure] 

The DBS penetration rate is highest in rural areas, but growing most 
rapidly in suburban and urban areas. Between 2001 and 2004, the DBS 
penetration rate grew 15 percent in rural areas to 29 percent of rural 
households, 32 percent in suburban areas to 18 percent of suburban 
households, and 50 percent in urban areas to 13 percent of urban 
households. 

The degree and type of competition influences the DBS penetration rate. 
In areas with no cable service, the DBS penetration rate is about 53 
percentage points greater than in areas where cable service is 
available. Where cable service is available, cable operators 
increasingly offer advanced services. The DBS penetration rate is 
approximately 20 percentage points greater in areas where cable 
operators are not providing advanced services, compared with areas 
where these services are available. While relatively few areas have 
more than one wire-based cable operator, in these areas the DBS 
penetration rate is 8 percentage points lower than in areas with only 
one cable operator.

In addition to the differences in DBS penetration rates across rural, 
suburban, and urban areas, and differences associated with the degree 
and type of cable competition, additional geographic and competitive 
factors also influence the DBS penetration rate. For example, the DBS 
penetration rate is lower in areas with a high prevalence of multiple-
dwelling units, such as apartments. Additionally, the DBS penetration 
rate is higher in areas where DBS providers offer local broadcast 
stations (such as ABC and NBC affiliates) directly to their subscribers.

The Federal Communications Commission provided technical comments on a 
draft of this report that we incorporated where appropriate.

United States Senate: 

For many years, cable television operators faced little competition in 
the market for subscription video service. However, in 1994, a new type 
of competitor emerged: direct broadcast satellite (DBS). Subscribers to 
DBS service use small reception dishes to receive television 
programming beamed down from satellites that orbit over the equator. 
DBS was originally most popular in rural areas, where cable service was 
often limited or did not exist. In recent years, DBS has also become 
popular in suburban and urban markets. In particular, the 
competitiveness of DBS was bolstered when the Congress enacted the 
Satellite Home Viewer Improvement Act of 1999, which allows DBS 
carriers to provide local broadcast signals, such as the affiliates of 
ABC and NBC, directly to subscribers.[Footnote 1] Today, the two 
primary DBS providers--DIRECTV® and EchoStar--provide local broadcast 
signals in 156 of 210 television markets. 

You asked us to provide information on the extent to which DBS is 
competitive with cable under varied market circumstances. Specifically, 
this report provides information on (1) how DBS subscribership has 
changed since 2001; (2) how DBS penetration rates (that is, the 
percentage of households subscribing to DBS) differ across urban, 
suburban, and rural areas; (3) how DBS penetration rates differ across 
markets based on the degree and type of competition provided by cable 
operators; and (4) the factors that appear to influence DBS penetration 
rates across cable franchise areas.[Footnote 2]

To respond to the objectives of this report, we gathered data on DBS 
subscribers from the Satellite Broadcasting and Communications 
Association (SBCA)[Footnote 3] and cable rates and services from the 
Federal Communications Commission (FCC). For the first and second 
objectives, we calculated the DBS penetration rate at the county level 
for the years 2001 to 2004. This allowed us to examine the trend in the 
DBS penetration rate for that period of time. We also classified 
counties as urban, suburban, and rural, based on the location of 
central cities and designations of metropolitan statistical areas 
(MSA), and calculated the DBS penetration rate for each of these 
geographic categories. For the third objective, we used data from 
Knowledge Network's 2004 The Home Technology Monitor[Footnote 4] survey 
to identify responding households that said cable service was not 
available to them, and to then examine the penetration of DBS service 
among these responding households, compared with those who said that 
cable service was available in their area. We also calculated the DBS 
penetration rate for cable franchise areas included in FCC's 2002 and 
2004 Cable Price surveys.[Footnote 5] Using data from FCC's surveys, we 
classified each cable franchise on the basis of (1) whether "advanced 
services"--such as cable modem and digital cable tiers of programming-
-were provided by cable operator and (2) whether there was a second 
wire-based provider in the market. We then calculated the DBS 
penetration rate for these different categories of cable franchise 
areas. For the fourth objective, we used an econometric model we 
previously developed that examines the competitive interaction of cable 
and DBS providers. Using data from 2004, the model considers the effect 
of various factors (such as the number of channels provided by the 
cable company) on cable rates, the number of cable subscribers, the 
number of channels that cable operators provide to subscribers, and the 
DBS penetration rate in areas throughout the United States.[Footnote 6] 
See appendix I for additional information on our scope and methodology 
and appendix II for the steps we took to ensure the reliability of the 
data we used to prepare this report. We found these data to be 
sufficiently reliable for the purposes of this report. 

We conducted our review from March 2004 to February 2005 in accordance 
with generally accepted government auditing standards. 

Results in Brief: 

Subscriptions to DBS service have grown rapidly since 2001. In July 
2001, about 15.5 million American households--about 13 percent of 
households--subscribed to a DBS service. By January 2004, about 21.3 
million households subscribed to a DBS service, or 17.4 percent of 
households. Thus, the number of DBS subscribers increased by 37.8 
percent during this 2-1/2 year time frame.[Footnote 7]

DBS penetration rates have been and remain highest in rural areas, but 
since 2001, DBS penetration has grown most rapidly in urban and 
suburban areas, where the penetration rates were originally low. In 
2001, DBS penetration rates were nearly 26 percent in rural areas, 14 
percent in suburban areas, and about 9 percent in urban areas. By 2004, 
DBS penetration rates had increased to about 29 percent in rural areas, 
18 percent in suburban areas, and 13 percent in urban areas, indicating 
a consistent pattern of higher DBS penetration rates in rural areas. In 
short, over the 2001 to 2004 time frame, the DBS penetration rate grew 
about 50 percent and 32 percent in urban and suburban areas, 
respectively, compared with a growth rate of 15 percent in rural areas. 

DBS penetration rates are affected by the degree and type of 
competition in a local market. Based on survey data, we found that 
relatively few American households--less than 9 percent--do not have 
the opportunity to purchase cable television service because it is not 
available where they live.[Footnote 8] However, in these areas, the DBS 
penetration rate is about 53 percentage points greater than it is in 
areas where cable television service is available. In areas where cable 
television service is available, cable operators are increasingly 
providing advanced services, such as digital cable, cable modem, and 
telephone service. In 2004, the DBS penetration rate was approximately 
20 percentage points greater in areas where cable operators were not 
providing advanced services, compared with areas where these services 
were available. Finally, in most areas, cable companies do not compete 
with other wire-based competitors, but in limited areas there is more 
than one wire-based provider of cable television service. Where more 
than one cable provider exists, the DBS penetration rate is 8 
percentage points lower than in areas with only one cable provider. 

Using an econometric model to control for the many factors that 
influence the DBS penetration rate, we identified three key geographic 
factors and three key competitive factors that influence the DBS 
penetration rate. Some of these findings confirm the findings discussed 
above based on descriptive statistics, and other findings could only be 
examined within the model. Regarding the geographic factors, we found 
that (1) the DBS penetration rate is lower in markets with a high 
prevalence of multiple dwelling units, such as apartments and 
condominiums; (2) the DBS penetration rate is lower in areas where, in 
order to face the transmitting satellite, the satellite dish must be 
installed at a relatively low angle, facing the horizon more than the 
sky; and (3) the DBS penetration rate is higher in nonmetropolitan 
areas. Regarding the competitive factors, we found that (1) the DBS 
penetration rate is lower in areas where the cable operator's system 
has greater system capacity;[Footnote 9] (2) the DBS penetration rate 
is lower in areas where there is more than one wire-based cable 
provider; and (3) the DBS penetration rate is higher in areas where DBS 
providers carry local broadcast stations, such as an ABC affiliate. 

We provided a draft of this report to the Federal Communications 
Commission (FCC) for their review and comment. FCC staff provided 
technical comments that we incorporated where appropriate. 

Background: 

Cable television service emerged in the late 1940s to fill a need for 
television service in areas with poor over-the-air reception, such as 
mountainous or remote areas. At that time, cable operators simply 
retransmitted the signals of local broadcast stations. By the late 
1970s, cable operators began to provide new cable networks,[Footnote 
10] such as HBO, Showtime, and ESPN, and the number of cable 
subscribers increased rapidly. Two significant changes occurred in the 
1990s and early 2000s. First, the Congress passed the Cable Television 
Consumer Protection and Competition Act of 1992 that, among other 
things, prohibited local franchising authorities from awarding 
exclusive (or monopoly) franchises to cable operators, thereby opening 
the door to wire-based competition. Second, cable operators began 
offering new services, such as digital cable, cable modem Internet 
access, and telephone, in addition to their basic video service. Today, 
many cable operators offer these advanced services in bundles with 
their basic video service. 

Since its introduction in 1994, direct broadcast satellite (DBS) 
service has grown dramatically and is now the primary competitor to 
cable operators. Subscribers to DBS service use a small reception dish 
to receive signals beamed down from satellites. Because DBS satellites 
orbit above the equator, a reception dish must point toward the 
southern sky, and households located in the northern part of the United 
States need to angle the dish more toward the horizon than households 
in the southern part of the United States. Unlike cable, which upgraded 
to digital service in recent years, DBS service has been a digital-
based service since its inception. DBS providers generally offer most 
of the same cable networks as cable operators. However, for many years 
DBS providers did not offer local broadcast stations to their 
subscribers in most instances because of copyright obstacles, obstacles 
that cable operators did not face. After the Congress passed the 
Satellite Home Viewer Improvement Act of 1999, which altered the 
copyright rules that applied to DBS providers, cable and DBS companies 
were placed on a more equal competitive footing. 

Subscription to DBS Has Grown Rapidly Since 2001: 

From 2001 to 2004, the aggregate number of U.S. households that 
subscribe to DBS television service grew rapidly. Figure 1 illustrates 
the growth in total DBS subscription and penetration rates for 2001 
through 2004. In July 2001, about 15.5 million households were served 
by DBS. By January 2004, about 21.3 million households were served by 
DBS--an increase of 37.8 percent in 2-1/2 years. Similarly, over the 
same period of time, the overall penetration rate of DBS rose from 13 
percent in 2001 to 17.4 percent in 2004--a 33.5 percent increase.

DBS Has the Greatest Penetration in Rural Areas, but Subscriber Growth 
Has Been Greater in Urban and Suburban Areas Since 2001: 

DBS penetration rates have been higher in rural areas than in suburban 
and urban areas throughout the last several years, as shown in figure 
2. From July 2001 to January 2004, DBS penetration has grown steadily 
in all three types of geographic areas. In 2001, penetration rates were 
highest in rural areas at 25.6 percent, followed by 13.9 percent in 
suburban areas and 8.6 percent in urban areas. As of January 2004, DBS 
penetration remained the highest in rural areas, growing to about 29 
percent, while it grew to 18 percent of suburban households and 13 
percent of urban households.

Although the DBS penetration rate in rural areas has been and remains 
higher than it is in other geographic areas, subscribership has grown 
more rapidly in suburban and urban areas than in rural areas from 2001 
to 2004. In fact, urban areas have experienced the highest growth in 
overall DBS subscribership. Figure 3 displays the percentage growth in 
total DBS subscribers and the percentage growth in DBS penetration 
rates in urban, suburban, and rural areas. From 2001 to 2004, DBS 
subscribership grew 55 percent in urban areas, 37 percent in suburban 
areas, and 17 percent in rural areas. In the same time period, the 
growth in penetration rates was also highest in urban areas, at 50.4 
percent, followed by suburban penetration growth at 32 percent, and 
rural penetration growth of 15 percent.

DBS Penetration Is Higher Where Cable Service Is Not Available, Where 
Cable Providers Do Not Offer Advanced Services, and Where Wire-Based 
Competitors Are Not Present: 

Less than 9 percent of American households do not have the opportunity 
to purchase cable television service because it is not available where 
they live. However, in these areas, the DBS penetration rate is about 
53 percentage points greater than in areas where cable television 
service is available. Where cable television service is available, 
cable operators are increasingly providing advanced services, such as 
digital cable, cable modem, and telephone service. In 2004, the DBS 
penetration rate was over 20 percentage points greater in areas where 
cable operators did not provide advanced services, compared with areas 
where these services were available. Finally, in some limited areas, 
cable companies compete with other wire-based competitors, and where 
there is more than one wire-based cable competitor, the DBS penetration 
rate was 8 percentage points lower than in areas without such an 
additional competitor. 

DBS Penetration Is Much Higher in Areas without Cable Service: 

Most households in the United States have access to cable television 
service. Using Knowledge Network's 2004 survey, we found that less than 
9 percent of responding households reported that cable television 
service was not available. According to FCC, households without access 
to cable television service generally reside in smaller and rural 
markets.[Footnote 11]

Where cable television service is not available, households are far 
more likely to purchase DBS service. In figure 4, we illustrate the 
percentage of households receiving television service through four 
different modes (over-the-air, cable, DBS, and other) for areas where 
households report that cable television service is available and where 
it is not available. In areas where cable television service is 
available, 65 percent purchase cable service, 16 percent use free over-
the-air television, and about 15 percent purchase DBS service. When 
cable television service is not available, a significant percentage of 
households--nearly 68 percent--purchase DBS service, while nearly all 
of the remainder--31 percent--rely on over-the-air television.

DBS Penetration Is Much Higher in Areas Where Cable Operators Do Not 
Offer Advanced Services: 

Since 2001, the percentage of cable operators providing advanced 
services (digital cable, cable modem, and telephone services) has 
increased. In figure 5, we illustrate the percentage of cable operators 
providing no advanced services; one or more, but not all, advanced 
services; and all three advanced services based on FCC's annual survey 
of cable franchises.[Footnote 12] In 2001, over 18 percent of cable 
operators did not provide advanced services, while less than 3 percent 
did not provide advanced services by 2004. At the same time, the 
percentage of cable operators providing all three advanced services 
increased from 16 percent in 2001 to 26 percent in 2004. In 2004, most 
cable operators (about 66 percent) provided both digital cable and 
cable modem services, but not telephone service.

(Digital Cable, Cable Modem, and Telephone), 2001--2004:

[End of figure]

In areas where cable operators do not provide advanced services, the 
DBS penetration rate is significantly greater than in areas where cable 
operators provide advanced services. In figure 6, we illustrate the DBS 
penetration rate for 2001, 2002, and 2004 based on the availability of 
advanced services from cable operators. In 2004, the DBS penetration 
rate was over 36 percent in areas where cable operators did not provide 
advanced services, compared with approximately 16 percent in areas 
where cable operators provided one or more, but not all, advanced 
services, and only 14 percent in areas where cable operators provided 
all three advanced services. In fact, the DBS penetration rate 
increased modestly since 2001 in areas where cable operators provide 
one or more advanced services. However, the DBS penetration rate 
increased 12 percentage points since 2001 in areas where cable 
operators do not provide advanced services.

DBS Penetration Is Lower in Areas Where There Is Wire-Based Cable 
Competition: 

Although the Telecommunications Act of 1996 sought to increase wire-
based competition, few American households have a choice among 
companies providing television service via wire-based facilities. In a 
2005 report, FCC noted that few franchise areas--about 1 percent--have 
effective competition based on the presence of a wire-based 
competitor.[Footnote 13] These competitors include telephone companies, 
electric and gas utilities, and broadband service providers. 

In areas with more than one wire-based cable provider, the DBS 
penetration rate is lower compared with areas with only one wire-based 
provider. In figure 7, we illustrate the DBS penetration rate for 2004 
in cable franchise areas with and without wire-based cable competition. 
The DBS penetration rate is 18 percent in areas without wire-based 
competition and 10 percent in areas with wire-based competition.

Several Geographic and Competitive Factors Are Associated with 
Different Levels of DBS Penetration across Cable Franchise Areas: 

We found that three key geographic factors and three key competitive 
factors influence DBS penetration rates in cable franchise areas 
throughout the United States. Regarding geographic factors, we found 
that (1) the DBS penetration rate is lower in areas with a high 
prevalence of multiple dwelling units, such as apartments and 
condominiums; (2) the DBS penetration rate is lower in areas where the 
angle at which the satellite dish must be installed is relatively low, 
such that the satellite points more toward the horizon than toward the 
sky; and (3) the DBS penetration rate is higher in nonmetropolitan 
areas. In terms of competitive factors, we found that (1) the DBS 
penetration rate is lower in areas where the cable operator's system 
has greater system capacity; (2) the DBS penetration rate is lower in 
areas where there is more than one wire-based cable provider; and (3) 
the DBS penetration rate is higher in areas where DBS providers carry 
local broadcast stations, such as an ABC affiliate. 

Key Geographic Factors Influence DBS Penetration Rates: 

Using an econometric model to control for the many factors that 
influence the DBS penetration rate, we identified three geographic 
factors that influenced the DBS penetration rate in cable franchise 
areas in 2004; see appendix III for a full explanation of, and results 
from, our econometric model. 

* The DBS penetration rate is lower in areas with a relatively large 
number of housing units represented by multiple dwelling units (such as 
apartments and condominiums). A 10 percent increase in the percentage 
of housing units represented by multiple dwelling units is associated 
with a 2.5 percent decrease in the DBS penetration rate. One possible 
explanation for this result is that residents of multiple dwelling 
units are more likely to encounter greater difficulty installing a DBS 
satellite dish, since the dish requires a clear line of sight to the 
southern sky.[Footnote 14]

* The DBS penetration rate is lower in areas where, to see the southern 
sky, the satellite dish must be pointed more toward the horizon than up 
at the sky. In general, the farther north one is within the United 
States, the more the dish must be angled toward the horizon to see the 
satellite over the equator. We found that a 1 percent decrease in the 
angle at which the DBS satellite dish must be set at is associated with 
a 1 percent decrease in the DBS penetration rate. A possible 
explanation for this result is that a satellite dish facing the horizon 
is less likely to have a clear line of sight to the southern sky 
because of interference from surrounding buildings or trees. 

* The DBS penetration rate is generally higher in nonmetropolitan 
areas. The DBS penetration rate is about 41 percent greater in cable 
franchise areas outside metropolitan areas compared with cable 
franchise areas within metropolitan areas. This result is consistent 
with the results discussed above for 2001 to 2004 and may be attributed 
to the early popularity of satellite service in rural areas. 

Key Competitive Factors Influence DBS Penetration Rates: 

Using the same econometric model, we also identified three competitive 
factors that influence the DBS penetration rate in cable franchise 
areas in 2004. 

* The DBS penetration rate is lower in areas where the cable operator's 
system has greater capacity. A 10 percent increase in the cable 
operator's system capacity is associated with a 2.4 percent decrease in 
the DBS penetration rate. With greater system capacity, a cable 
operator can provide more channels and advanced services, such as 
digital cable, cable modem, and telephone services. Thus, greater 
system capacity allows the cable operator to provide a compelling 
alternative to DBS service that can contribute to lower DBS penetration 
rates. This result is consistent with the lower DBS penetration rate in 
areas where cable operators provided advanced cable services for 2001 
to 2004 that we discussed above. 

* The DBS penetration rate is lower in areas with wire-based cable 
competition, compared with areas without wire-based competition. In 
particular, we found that DBS penetration rates are about 37 percent 
lower in areas with wire-based cable competition compared with areas 
without wire-based competition. Again, this result is consistent with 
the results discussed above. With wire-based competition, additional 
companies are competing for customers. The addition of a second cable 
operator can attract some customers who might otherwise have purchased 
DBS service, thereby reducing the DBS penetration rate. 

* The DBS penetration rate is higher in areas where DBS customers can 
receive local-into-local service. Local-into-local service allows DBS 
subscribers to receive the local broadcast stations in their area 
(e.g., the ABC, CBS, Fox, and NBC affiliates) from the DBS provider, 
just as cable subscribers receive local broadcast stations from their 
cable operator. Since individual programming appearing on broadcast 
stations generally has higher ratings than individual programming 
appearing on cable channels, the ability of DBS providers to offer 
local broadcast stations to their customers remains an important 
competitive factor. We found that where local-into-local service is 
available, the DBS penetration rate is about 12 percent higher than 
areas where local-into-local is not available. 

Agency Comments and Our Evaluation: 

We provided a draft of this report to the Federal Communications 
Commission (FCC) for its review and comment. FCC staff provided 
technical comments that we incorporated, where appropriate. 

Industry Participants' Comments: 

We provided a draft of this report to the National Cable and 
Telecommunications Association (NCTA) and the Satellite Broadcasting 
and Communications Association (SBCA) for their review and comment. 
NCTA provided no comments. SBCA officials noted that, in addition to 
the factors we discuss in the report, the inability of DBS providers to 
carry certain programming developed by cable operators also influences 
the DBS penetration rate in certain markets. In particular, SBCA noted 
that FCC's program access rules require that vertically integrated 
cable operators make satellite-delivered programming available to 
competing subscription video providers, such as DBS providers, but that 
the program access rules do not apply to terrestrially delivered 
programming. SBCA officials note that the ability of cable operators to 
deliver programming terrestrially, especially popular programming such 
as regional sports networks, and therefore deny DBS providers access to 
this programming, negatively affects the DBS penetration rate in 
certain markets.

Appendixes: 

Appendix I: Scope and Methodology: 

To respond to the first and second objectives--to provide information 
on how direct broadcast satellite (DBS) subscribership has changed 
since 2001 and how the DBS penetration rate differs across urban, 
suburban, and rural areas--we gathered data on DBS subscribers from the 
Satellite Broadcasting and Communications Association (SBCA). SBCA 
provided us with the number of DBS subscribers by ZIP Code™[Footnote 
15] for the two DBS providers, DIRECTV® and EchoStar. Using information 
from the Census Bureau and a private vendor, we matched the zip codes 
to counties and calculated the number of DBS subscribers in each county 
throughout the United States. We also gathered data on housing unit 
projections from the Census Bureau, which, when combined with the 
number of DBS subscribers, allowed us to calculate the DBS penetration 
rate by county for July 2001 to January 2004. This allowed us to 
examine changes in the DBS penetration rate for that period of time. 
Further, using data from the Office of Management and Budget, we 
classified counties as urban, suburban, and rural, based on the 
location of central cities and designations of metropolitan statistical 
areas (MSA). This allowed us to calculate the DBS penetration rate for 
each of these geographic categories. 

To respond to the third objective--to provide information on the DBS 
penetration rate based on the degree and type of competition--we used 
two different methodologies. First, to examine the DBS penetration rate 
in areas with and without cable service, we used survey data from 
Knowledge Network's The Home Technology Monitor: Spring 2004 Ownership 
and Trend Report. Knowledge Networks is a survey research firm that 
conducted a consumer survey on household television characteristics. 
Knowledge Networks interviewed 2,471 randomly sampled telephone 
households, asking questions regarding the household's ownership of 
television equipment and use of television service; see appendix II for 
a discussion of the steps we took to evaluate the reliability of 
Knowledge Network's data. The survey included questions regarding 
whether the household had cable service available and which method the 
household used to receive television (e.g., over-the-air, cable, or 
DBS). We used these data to identify the percentage of households 
receiving DBS service in areas with and without cable service. Second, 
to examine the DBS penetration rate in areas with advanced cable 
services and wire-based cable competition, we used data from FCC's 
annual Cable Price Survey. We used data from FCC's 2002 and 2004 
surveys, which included questions regarding the availability of digital 
cable, cable modem, and telephone service and the presence of wire-
based competition. We matched individual zip codes to the cable 
franchise areas that formed the unit of analysis in FCC's survey. When 
combined with the count of DBS subscribers by zip code from SBCA, we 
calculated the DBS penetration rate for each cable franchise area in 
FCC's survey. We used these data, combined with cable operators' 
responses to FCC's survey regarding advanced services and wire-based 
competition, to calculate the DBS penetration rate under these various 
scenarios. 

To respond to the fourth objective--to provide information on the 
factors that appear to influence the DBS penetration rate in cable 
franchise areas--we used an econometric model we previously developed 
that examines the effect of competition on cable rates and service and 
the DBS penetration rate.[Footnote 16] Using data from FCC's 2004 Cable 
Price Survey, the model considered the effect of various factors on 
cable rates, the number of cable subscribers, the number of channels 
that cable operators provide to subscribers, and the DBS penetration 
rate for areas throughout the United States. See appendix III for a 
more detailed explanation of, and results from, our econometric model.

Appendix II: Data Reliability: 

To respond to the objectives of this report, we relied extensively on 
three data sets and took steps to ensure the reliability of these data. 
The data sets we relied on include the Federal Communications 
Commission's (FCC) 2002 and 2004 Cable Price surveys, direct broadcast 
satellite (DBS) subscriber counts by zip code from the Satellite 
Broadcasting and Communications Association (SBCA), and Knowledge 
Network's 2004 The Home Technology Monitor survey. In this appendix, we 
explain the steps we took to ensure that these data were sufficiently 
reliable for the purposes of our work. 

FCC's Cable Price surveys: 

FCC annually surveys approximately 700 cable franchises to fulfill a 
congressional mandate to report on average cable rates for cable 
operators found to be subject to "effective competition"--a legally 
defined term--compared with operators not subject to effective 
competition. In previous testimonies and a report, we have noted 
weaknesses with FCC's survey, including insufficient instructions and 
inaccuracies in the classification of the competitive status of cable 
operators.[Footnote 17] In response to our recommendations, FCC has 
taken several steps to improve the reliability of its survey, including 
editing the survey document and correcting inaccurate classifications 
of the competitive status of cable franchises. Additionally, FCC 
conducts follow-ups with survey respondents and edits survey data when 
inaccuracies are apparent. 

We used FCC's 2002 and 2004 Cable Price surveys to identify areas where 
cable operators provided advanced services and also for information on 
price, number of channels, and other operating data necessary for our 
cable-satellite econometric model. Because our use of data from FCC's 
surveys was important in a comparative manner, rather than an absolute 
sense--that is, our primary concern with cable rates was the relative 
level of rates between cable franchises, rather than the absolute rate 
in a particular cable franchise--it is not important for our use that 
the data be precise. We conducted logic tests to identify any 
observations with apparent inaccuracies in the variables of interest 
for our work. We determined that the data were sufficiently reliable 
for our analysis. 

SBCA's DBS Subscriber Counts: 

SBCA possesses data on the number of DBS subscribers by zip code. To 
respond to the objectives of this report, we sent SBCA a letter 
identifying the specific data elements we required. SBCA officials 
prepared a set of data sets consistent with our needs. We conducted 
logic tests on SBCA's data and identified some inconsistencies, which 
we discussed with SBCA officials. SBCA officials subsequently took 
steps to resolve these inconsistencies. Based on the revised data we 
received from SBCA and our subsequent tests, we determined that the 
data were sufficiently reliable for our analysis. 

Knowledge Network's The Home Technology Monitor: Spring 2004 Ownership 
and Trend Report: 

To obtain information on the availability of cable service and types of 
television service used by U.S. households, we purchased existing 
survey data from Knowledge Networks Statistical Research. This survey 
was completed with 2,375 of the estimated 5,075 eligible sampled 
individuals for a response rate of 47 percent; partial interviews were 
conducted with an additional 96 people, for a total of 2,471 
individuals completing some of the survey questions. The survey was 
conducted between February 23 and April 25, 2004. Because we did not 
have information on those contacted who chose not to participate in the 
survey, we could not estimate the impact of the nonresponse. Our 
findings will be biased to the extent that the people at the 53 percent 
of the telephone numbers that did not yield an interview have 
experiences with television service or equipment that are different 
from the 47 percent of our sample who responded. However, distributions 
of selected household characteristics (including presence of children, 
race, and household income) for the sample and the U.S. Census estimate 
of households show a similar pattern. 

To assess the reliability of these survey data, we reviewed 
documentation of survey procedures provided by Knowledge Networks and 
questioned knowledgeable officials about the survey process and 
resulting data. We determined that the data were sufficiently reliable 
for the purposes of this report.

Appendix III: Cable-Satellite Econometric Model: 

This appendix describes our econometric model of cable-satellite 
competition. In particular, we discuss (1) the specification of the 
model, (2) the data sources used for the model, (3) the merger of 
various data sources into a single data set, (4) the descriptive 
statistics for variables included in the model, (5) the estimation 
methodology and results, and (6) alternative specifications. 

Specification of Econometric Model of Cable-Satellite Competition: 

We developed an econometric model to examine the influence of various 
factors, including those describing aspects of cable competition at the 
local level, on local DBS penetration rates. Estimating the importance 
of various factors on the DBS penetration rate is complicated by the 
possibility that the DBS penetration rate in an area may help 
determine, but also be determined by, in part, the local cable price in 
that area. One statistical method applicable in this situation is to 
estimate a system of structural equations in which certain variables 
that may be simultaneously determined are estimated jointly. In our 
previous reports, we estimated a four-equation structural model in 
which cable prices, the number of cable subscribers, the number of 
cable channels, and the DBS penetration rate were jointly 
determined.[Footnote 18] We use this same general structure again, this 
time using the most recent information available from FCC's 2004 Cable 
Price Survey and contemporaneous satellite subscriber information 
provided by the Satellite Broadcasting and Communications Association. 
We made some minor modifications because of, for example, changes in 
the subscription video market. 

We estimated the following four-equation structural model of the 
subscription video market: 

* DBS penetration rate in a local market is hypothesized to be related 
to (1) cable prices per channel; (2) the DBS companies' provision of 
local stations in the franchise area; (3) the size of the television 
market as measured by the number of television households; (4) the age 
of the cable franchise; (5) the median household income of the local 
area; (6) cable system capacity in terms of megahertz; (7) a dummy 
variable for areas outside metropolitan areas; (8) the percentage of 
multiple dwelling units; (9) the angle, or elevation, at which a 
satellite dish must be fixed to receive a satellite signal in that 
area; and (10) the presence of a nonsatellite competitor. The DBS 
penetration rate variable is defined as the number of DBS subscribers 
in a franchise area expressed as a proportion of the total number of 
housing units in the area. As hypothesized, the DBS penetration rate is 
expected to depend on the prices set by the cable provider as well as 
on the demand, cost, and regulatory conditions in the subscription 
video market that directly affect DBS. 

* Cable prices are hypothesized to be related to (1) the number of 
channels, (2) the number of cable subscribers, (3) the DBS penetration 
rate, (4) the DBS companies' provision of local stations in the 
franchise area, (5) the size of the television market as measured by 
the number of television households, (6) horizontal concentration, (7) 
vertical relationships, (8) the presence of a nonsatellite competitor, 
(9) regulation, (10) average wages, and (11) population density. The 
cable price variable used in the model is intended to reflect the total 
monthly rate charged by a cable franchise to the typical subscriber. 
The explanatory variables in the cable price relationship are 
essentially cost and market structure variables. 

* Number of cable subscribers is hypothesized to be related to (1) 
cable prices per channel, (2) the DBS penetration rate, (3) the number 
of broadcast stations, (4) urbanization, (5) the age of the cable 
franchise, (6) the number of homes passed by the cable system, (7) the 
median household income of the local area, and (8) the presence of a 
nonsatellite competitor. The number of cable subscribers is defined as 
the number of households in a franchise area that subscribe to the most 
commonly purchased programming tier. This represents the demand 
equation for cable services, which depends on rates and other demand-
related factors. 

* Number of channels is hypothesized to be related to (1) the number of 
cable subscribers, (2) the DBS penetration rate, (3) the size of the 
television market as measured by the number of television households, 
(4) the median household income of the local area, (5) cable system 
capacity in terms of megahertz, (6) the percentage of multiple dwelling 
units, (7) vertical relationships, and (8) the presence of a 
nonsatellite competitor. The number of channels is defined as the 
number of channels included in the most commonly purchased programming 
tier. The number of channels can be thought of as a measure of cable 
programming quality and is explained by a number of factors that 
influence the willingness and ability of cable operators to provide 
high-quality service and consumers' preference for quality.

Data Sources Used for the Econometric Model: 

We required several data elements to build the data set used to 
estimate this model. The following is a list of our primary data 
sources. 

* We obtained data on cable prices and service characteristics from the 
2004 Cable Price Survey that FCC conducted as part of its mandate to 
report annually on cable prices. FCC's survey asked a sample of cable 
franchises to provide information, as of January 1, 2004, about a 
variety of items pertaining to cable prices, service offerings, 
subscribership, franchise area reach, franchise ownership, and system 
capacity. We used the survey to define measures of each franchise 
area's cable prices, number of subscribers, and number of channels as 
described above. In addition, we used the survey to define variables 
measuring (1) system megahertz (the capacity of the cable system in 
megahertz), (2) homes passed by the cable system serving the franchise 
area and perhaps other franchises in the same area, (3) regulation--a 
dummy variable equal to 1 if the franchise is subject to rate 
regulation of its Basic Service Tier, (4) horizontal concentration--a 
dummy variable equal to 1 if the franchise area is affiliated with one 
of the largest MSOs with at least 1 million subscribers nationally, and 
(5) the status of nonsatellite competition--a dummy variable equal to 1 
if the franchise faced competition from a second wireline company that 
provides cable service. 

* From the Satellite Broadcasting and Communications Association, we 
obtained DBS subscriber counts as of January 2004 for each zip code in 
the United States. We used this information to calculate the number of 
DBS subscribers in a cable franchise area, which, when divided by the 
number of housing units, was used to define the DBS penetration rate. 

* We used the most recent data from the Census Bureau to obtain the 
following demographic information for each franchise area: housing 
units, median household income, proportions of urban and rural 
populations, housing units accounted for by structures with more than 
five units (multiple dwelling units), population density, and 
nonmetropolitan statistical areas. 

* For average wage, we used May 2003 estimates for Installation, 
Maintenance, and Repair Occupations from the Bureau of Labor 
Statistics' (BLS) National Occupational Employment and Wage Estimates. 
We used metropolitan area data for most franchise areas, and state-
level data for those franchise areas located outside of metropolitan 
areas. 

* We used data from BIA MEDIA AccessPro™ to determine the number of 
broadcast television stations in each television market. 

* To define the dummy variable indicator of vertical integration, we 
used information on the corporate affiliations of the franchise 
operators provided in FCC's survey. We used this information in 
conjunction with industrywide information on vertical relationships 
between cable operators and suppliers of program content gathered by 
FCC in its Tenth Annual Report on the status of competition in the 
market for delivery of video programming. 

* From Nielsen Media Research, we acquired information to determine the 
number of television households in each designed market area (DMA), or 
television market, and the DMA in which each cable franchise was 
located. 

* We used information from the two DBS companies (DIRECTV® and 
EchoStar) to identify DMAs in which these companies provide local 
stations and, if local stations are available, when the companies 
initiated this service. We used this to construct a measure of local 
station availability, as well as alternative specifications presented 
in the final section. 

* Based on a zip code associated with each cable franchise area, we 
determined the necessary satellite dish elevation for each area based 
on information available from the Web pages of the two DBS companies. 

Merging Various Data Sources into a Single Data Set: 

The level of observation in our model is the local cable 
franchise.[Footnote 19] Many of the variables we used to estimate our 
model, such as each cable franchise's price, come directly from FCC's 
Cable Price Survey. However, we also created variables describing 
competitive, geographic, and economic conditions in each franchise 
area. For these variables, we used information from other sources. For 
example, we obtained median household income and the extent of multiple 
dwelling units from Census Bureau data, and derived the DBS penetration 
rate from information provided by the Satellite Broadcasting and 
Communications Association. Generally, these data are reported at other 
geographic levels, and we describe briefly the process by which we 
merged these different data sources. 

Cable franchise areas take a variety of jurisdictional forms, such as 
city or town, or unnamed, unincorporated area. As a consequence, they 
do not correspond in many cases to well-recognized geographical units, 
such as Census places, for which other data are readily available. Our 
approach to identifying the geographic extent of each franchise area 
and relating information processed at different geographic levels to 
each franchise area is similar to that we have used and described in 
detail in our previous reports. In general, we used information in 
FCC's survey identifying franchise community name and type (such as 
city or town) to match to Census geographic identification codes for 
particular places or county subdivisions that do correspond to Census 
geography. In particular, we used 2000 Census information on the number 
of housing units in these jurisdictions as the basis for our measure of 
DBS penetration. For other franchises, however, the link to Census 
records was not as direct. For franchises in unincorporated unnamed 
areas, for example, and those whose franchise areas represent a section 
of the associated community (which occurs in some large cities[Footnote 
20]), we acquired additional information on the geographic boundaries 
of the franchise areas.[Footnote 21]

The satellite subscriber information we obtained was organized by zip 
code. In order to link these subscriber counts to franchise area 
geographies, we determined the zip code or zip codes associated with 
each franchise. Because zip codes often do not share boundaries with 
other geographies, one zip code can be associated with more than one 
cable franchise area. Also, many franchises, particularly larger ones, 
span many zip codes. Therefore, we needed to identify the zip code or 
codes in each franchise area as well as the degree to which each of 
those zip codes is contained in each franchise area to calculate the 
degree of satellite penetration for each franchise area. We 
accomplished this by using software designed to relate various levels 
of census geography to one another.[Footnote 22] For most franchise 
areas--that is, those that correspond to census places, county 
subdivisions, or entire counties--we were able to use this software to 
relate census places, county subdivisions, or other census geographies 
directly to the zip codes that corresponded to those areas and to 
calculate the share of each zip code's population according to the 2000 
Census that was contained in that area. We used these population shares 
to allocate shares of each zip code's total DBS subscribers to the 
relevant franchise area, and then summed the resulting subscribers 
across all zip codes in that franchise area.[Footnote 23] We defined 
the penetration by dividing this subscriber total by an estimate of the 
housing units in that franchise area in January 2004.[Footnote 24]

As part of the process of identifying the zip codes associated with 
each franchise area, we identified a key zip code that we used for 
linking other data items. We used Census data organized at the zip code 
level to assign demographic data, such as income and the extent of 
multiple dwelling units, to each franchise area. We also used this key 
zip code to attach information concerning the proper satellite dish 
elevation. 

We assigned other information to each franchise on the basis of the 
franchise's county, state, or metropolitan area. We assigned wage data 
from BLS at the metropolitan or state level and we assigned 
nonmetropolitan status, percentage of urban population, and the Nielsen 
television market of each franchise at the county level.[Footnote 25] 
Information on the provision of local stations by DBS companies, which 
occurs at the television market level, was then assigned to each 
franchise. 

Descriptive Statistics for Variables Included in the Econometric Model: 

Table 2 provides basic statistical information on all of the variables 
included in the cable-satellite competition model. We calculated these 
statistics using 624 observations in our data set. We excluded those 
franchises sampled by FCC that were municipally operated or that 
competed directly with municipally operated franchises because we 
believe that these cable franchises are likely to be operated 
differently from the majority of other franchises.

Estimation Methodology and Results: 

We employed the Three-Stage Least Squares (3SLS) method to estimate our 
model.[Footnote 26] Table 3 includes the estimation results for each of 
the four structural equations. All of the variables, except dummy 
variables,[Footnote 27] are expressed in natural logarithmic 
form.[Footnote 28] This means that coefficients can be interpreted as 
"elasticities"--the percentage change in the value of the dependent 
variable associated with a 1 percent change in the value of an 
independent, or explanatory, variable. The coefficients on the dummy 
variables are elasticities in decimal form.

[End of table]

We found that several factors related to the geographical conditions 
influence the DBS penetration rate. Specifically, as shown in table 3, 
DBS penetration rates are likely to be significantly higher in 
nonmetropolitan areas. This could be associated with the historical 
development of satellite service, which had been marketed for many 
years in smaller and more rural areas. Additionally, the DBS 
penetration rate is higher in areas that require a relatively higher 
angle or elevation at which the satellite dish is mounted and is lower 
in areas where there are more multiple dwelling units. These two 
factors can be associated with the need of DBS satellite dishes to 
"see" the satellite: A dish aimed more toward the horizon (as opposed 
to aimed higher in the sky) is more likely to be blocked by a building 
or foliage, and people in multiple dwelling units often have fewer 
available locations to mount a satellite dish. 

Additionally, we found that several factors related to competitive 
conditions influence the DBS penetration rate. As shown in table 3, our 
model results indicate that in cable franchise areas where local 
broadcast stations are available from one or both DBS providers, the 
DBS penetration rate is approximately 12 percent higher than in areas 
where local stations are not available via satellite.[Footnote 29] This 
finding suggests that in areas where local stations are available from 
one or both DBS providers, consumers are more likely to subscribe to 
DBS service and, therefore, DBS appears to be more competitive with 
cable than in areas where local stations are not available from a DBS 
provider. 

We did not find that DBS companies' provision of local broadcast 
stations is associated with lower cable prices. In table 3, the 
estimate is, in fact, positive, although not statistically significant, 
and we therefore cannot reject the hypothesis that provision of local 
broadcast stations has no impact on cable prices. However, we found 
that cable prices were approximately 16 percent lower in areas where a 
second cable company--known as an overbuilder--provides service. 
Finally, cable prices are higher in areas where the cable company 
provides more channels, indicating that consumers are generally willing 
to pay for additional channels and that providing additional channels 
raises a cable company's costs. Additionally, we found that DBS 
penetration rates are lower in cable franchise areas where a second 
wire-based competitor is present; in these areas, the DBS penetration 
rate is 37 percent lower compared with similar areas where a second 
wire-based competitor is not present. 

Alternative Specifications: 

We considered alternative specifications under which we expanded the 
definition of local broadcast stations to account for (1) whether one 
or both DBS companies offer local stations and (2) the length of time 
that DBS companies have provided local stations. To conduct this 
analysis, we included several additional variables: "Both DBS companies 
provide" equals 1 if both DBS companies offer local stations in the 
cable franchise area, "One DBS company provides" equals 1 if only one 
DBS company offers local stations, "Long-term" equals 1 if either or 
both DBS companies have offered local stations in the cable franchise 
area for more than 3 years as of January 2004, "Short-term" equals 1 if 
local stations have been available for less than 3 years, "Both long-
term" equals 1 if both DBS companies have offered local stations in the 
cable franchise area for more than 3 years as of January 2004, and 
"Both otherwise" equals 1 if local stations have otherwise been 
available from both DBS companies. 

We report the results of these alternative specifications only for the 
DBS penetration equation because we are primarily interested in their 
affects on DBS penetration and we found little impact on the other 
equations in the model. We present the results for four different 
specifications in table 4. In general, there is evidence that the 
longer that local stations have been available in a local area, the 
larger will be the increase in the local DBS penetration rate, and that 
the increase in the local DBS penetration rate is greater in those 
areas in which both DBS companies provide local stations.

FOOTNOTES

[1] In late 2004, the Congress passed and the President signed the 
Satellite Home Viewer Extension and Reauthorization Act of 2004. This 
act may further enhance the competitiveness of DBS providers by, for 
example, permitting DBS providers to deliver broadcast signals that are 
"significantly viewed" within a local market but originate from outside 
that local market. 

[2] At the community level, cable operators obtain a franchise 
agreement under agreed-upon terms and conditions from a franchising 
authority, such as a city, township, or county. The franchise agreement 
permits the cable operator to provide service in the jurisdiction. 

[3] SBCA is a national trade association representing the satellite 
industry. Its members include DBS, C-band, satellite radio, and other 
satellite service providers, among others. 

[4] Knowledge Networks is a survey research firm that had conducted a 
consumer survey on household television characteristics. The survey 
provided the responses of 2,471 randomly selected American households. 

[5] FCC conducts an annual survey of a random sample of cable franchise 
areas to gather information about cable pricing and other related 
issues. 

[6] This four equation model is an adaptation of a model that GAO 
developed and discussed in three previous reports. See GAO, 
Telecommunications: The Effect of Competition from Satellite Providers 
on Cable Rates, RCED-00-164 (Washington, D.C.: July 18, 2000);

in the Cable Television Industry, GAO-04-8 (Washington, D.C.: Oct. 24, 
2003). 

[7] The data cover 2-1/2 years, rather than 3 years, because FCC 
changed the time frame of its survey from July to January in 2004. 

[8] The percentage of households with cable service available has been 
a subject of controversy. Different industry participants, using 
different data sources and different bases of comparison, arrive at 
different figures. Using industry data, FCC noted that the percentage 
of homes with a television passed by cable must be less than 97.8 
percent. Alternatively, the National Rural Telecommunications 
Cooperative reports that 22.4 million households (or about 20 percent) 
lack access to cable service. We used a survey of a random sample of 
households to arrive at the 9 percent figure. 

[9] System capacity is measured in terms of the system megahertz. 
Systems with larger capacity are able to provide more channels and 
other services to their subscribers. 

[10] Today, a variety of subscription video providers, in addition to 
cable operators, deliver these networks to their subscribers. For 
consistency, we refer to these networks as cable networks.

[19] We define a cable franchise in terms of its FCC assigned Community 
Unit Identification (CUID) number. 

[20] Many large cities, such as New York City, Los Angeles, and 
Chicago, have multiple cable franchise areas. 

[21] For those jurisdictions for which there were multiple franchises, 
including counties with franchises in unincorporated unnamed areas, we 
attempted to define more precise geographical boundaries for each 
franchise. Specifically, we contacted local government offices 
responsible for cable franchise oversight and received maps or other 
descriptive information linking the specific franchise areas to zip 
codes, census tracts, local government districts, or some other 
boundary information. 

[22] In particular, we used the MABLE/Geocorr correspondence engine 
[Hyperlink, http://mcdc2.missouri.edu/websas/geocorr2k.html]. MABLE is 
an acronym for Master Area Block Level Equivalency file. 

[23] As an illustration, assume we have a cable franchise area in the 
town of Anytown, which the MABLE software identifies as served by zip 
codes 12345 and 12346. Assume further that zip code 12345 had a 
population of 10,000 people in 2000, of which 8,000 were in Anytown 
proper and 2,000 were in the surrounding unincorporated area, and zip 
code 12346 had a population of 12,000 people, of which 6,000 were in 
Anytown. In this case, 80 percent of the 12345 zip code and 50 percent 
of the 12346 populations are associated with Anytown, so that our 
approach would assign 80 percent of the satellite subscribers in zip 
code 12345 and 50 percent of those in 12346 to the cable franchise in 
the town of Anytown. Because we defined the DBS penetration rate as the 
number of subscribers divided by the number of housing units, our 
approach would divide this estimate of the number of DBS subscribers in 
Anytown by the number of housing units reported in the 2000 Census for 
the town of Anytown. 

[24] We used county-level housing unit projections made by the Census 
Bureau to adjust the 2000 housing unit counts to January 2004. This 
adjustment process assumes that growth was uniform within the 
boundaries of each county. 

[25] In the Nielsen data, some counties are split between different 
television markets. In cases where a franchise's county was not 
uniquely placed in one television market, we used additional 
information on zip codes to assign the franchise to a television 
market. 

[26] We preferred 3SLS to Two-Stage Least Squares (2SLS) because 3SLS 
accounts for the contemporaneous relationships among cable rates, cable 
subscribers, cable channels, and DBS penetration by using all available 
information. Also, we assumed that price per channel in the subscriber 
equation is exogenous because cable providers simultaneously decide how 
many channels to provide and what to charge for a package of channels, 
rather than deciding how much to charge for each channel. 

[27] A dummy variable takes a value of 1 if a certain characteristic is 
present and a value of 0 otherwise. 

[28] The dummy variables in the model include the following: horizontal 
concentration of cable systems, vertical relationship, regulation, 
presence of nonsatellite competitor, DBS provision of local stations, 
and nonmetropolitan area. Also, because the natural log of 0 is 
undefined, we added 1 to the observed value of any continuous variable 
that can take the value of 0. 

[29] This magnitude is less than we found previously; using 2001 data, 
we found that the DBS penetration rate was about 40 percent higher in 
cable franchises in which local stations were offered by both DBS 
companies. The somewhat smaller impact of local stations could be 
because the DBS companies have introduced this service into many more 
areas, including some smaller television markets.
