Comcast and RadioShack Announce Comprehensive Broadband and Video Services Retail Agreement

Comcast products and services added to 1,800 RadioShack neighborhood stores, further expanding Comcast's retail distribution leadership

 Comcast Corporation (Nasdaq: CMCSA, CMCSK), and RadioShack Corporation

(NYSE: RSH), today announced a comprehensive retail agreement spanning both
high-speed Internet and digital cable services. This agreement adds more than
1,800 RadioShack retail locations immediately to Comcast's already sizeable
retail footprint. It also allows RadioShack to provide a robust broadband and
video solution to its customers in those markets.

"Our announcement with RadioShack further supports our continuing efforts
to offer Comcast services to consumers at a time and place that's convenient
for them. There is a neighborhood RadioShack within an estimated five minutes
of where 94 percent of all Americans either live or work," said Bob Faught,
senior vice president of retail sales for Comcast Online. "Consumers can
visit their local RadioShack, sign up for Comcast High-Speed Internet, for
example, bring home a self-install kit, and connect to the Internet later that
same day."

"Comcast is also setting a new standard for the broadband/cable industry -
now with an expanded retail presence spanning nearly 5,000 retail locations
nationwide," Faught continued.

"By offering Comcast's leading products and services in more than 1,800
RadioShack stores, we are continuing our tradition of providing consumers with
the best selection of products and services to fulfill their consumer
electronics needs," said Jim Hamilton, senior vice president, chief
merchandising officer for RadioShack Corporation. "Comcast is a natural fit,
and we're thrilled to have them as our partner."

According to Hamilton, customers can easily work with RadioShack's
knowledgeable sales associates to check service availability, choose between a
self-install kit or a professional installation, and order Comcast High-Speed
Internet Service and Comcast Digital Cable in each participating store.

For a limited time*, customers who sign up for Comcast High-Speed Internet
through RadioShack will receive the flagship 6Mbps Internet service for $19.99
for the first six (6) months. They will also receive a free self-install kit,
with a mail-in rebate and a free cable modem. Customers will have immediate
access to Comcast.net, Comcast's award-winning broadband portal where they can
quickly and easily check their e-mail, send Video Mail messages, access their
photos, news, entertainment, sports scores, kids' features, online games, and
more.

With Comcast Digital Cable, customers can enjoy more than 250 channels
including dozens of commercial-free premium movie channels including multiple
channels of HBO, Showtime, The Movie Channel, Cinemax, STARZ! and Encore, as
well as dozens of music channels - from jazz to country to classical to rock -
commercial-free, 24-hours a day. In addition, customers have access to ON
DEMAND, a growing library of 3,800 programs available any time, with
95-percent available at no additional charge.

Comcast Digital Cable also features an interactive, on-screen program
guide and remote that lets viewers choose movies and shows by time, category
or channel, and parental controls to help customers manage the programs their
families watch. Comcast's High-Definition Television service offers HDTV
programming from local and national broadcast networks, national cable
networks and regional sports networks. With digital video recorder service
from Comcast, customers can digitally record and store their favorite
television programs as well as pause and rewind "live" television. Comcast
