Comcast Will Introduce Two New, Faster Speed Tier Options and Will Double Speeds for Most Existing Customers for No Additional Cost

New Speed Options to Begin in Silicon Valley, Tri-Valley and Monterey, and Roll Out in San Francisco, Oakland and Remainder of Bay Later This Year

Comcast, (Nasdaq: CMCSA, CMCSK) the nation’s leading  provider of entertainment, information and communications products and services, today announced it  is making the leap from broadband to wideband with the launch of next-generation DOCSIS 3.0 in the Bay Area.  With wideband, Comcast will introduce a new echelon of Internet speed tiers, which will redefine the customer experience online and create a platform for Internet innovation in the years ahead.

With wideband, Comcast will offer the fastest speeds available today in the Bay Area, including the Extreme 50 tier with download speeds of up to 50 Mbps.  Wideband will also enable Comcast to double speeds for the majority of existing high-speed Internet customers at no additional cost.

“Wideband utilizes our existing fiber-optic network in neighborhoods across our footprint.  With this next generation of service, our customers’ online experience is dramatically enhanced,” said Steve White, Senior Vice President of Comcast’s California Region.  “And this is just the beginning.  Wideband, combined with our fiber-optic network, gives us the capability of meeting the needs of our customers for many years to come by offering even faster speeds in the future.”

Beginning today, Comcast’s new services will be available to residential homes (and beginning March 10 to all businesses) in the San Jose-Silicon Valley area (Alviso, Campbell, Cupertino, Los Altos, Los Gatos, Milpitas, Monte Sereno, Mount Hamilton, Mountain View, Saratoga, San Jose, Santa Clara and Sunnyvale), portions of the East Bay (Alamo, Antioch, Bay Point, Bethel Island, Brentwood, Byron, Castro Valley, Clayton, Clyde, Concord, Danville, Diablo, Discovery Bay, Dublin, Knightsen, Lafayette, Livermore, Martinez, Moraga, Oakley, Orinda, Pacheco, Pittsburg, Pleasant Hills, Pleasanton, Rossmoor, San Ramon, Sunol and Walnut Creek) and the Monterey-Salinas area (Carmel, Carmel Valley, Del Rey Oaks, Marina, Monterey, Pacific Grove, Pebble Beach, Salinas, Sand City, Seaside and Spreckels).  From the Monterey Peninsula to the Tri-Valley, customers will soon be surfing the web even faster.  The faster speeds will be available in other portions of the Bay Area later in 2009.

As part of the wideband deployment, Comcast will launch two new premium speed tiers to its residential and business class customers.  Both new services are ideal for households or businesses simultaneously using several computers or Internet-connected devices.  They also will appeal to those who simply want some of the fastest speeds available today:

New Residential Tiers

• Extreme 50, offering up to 50 Mbps of downstream speed and up to 10 Mbps of upstream speed at $139.95/month.* 
• Ultra, offering up to 22 Mbps of downstream speed and up to 5 Mbps of upstream speed at $62.95/month.*                                                               
• With Extreme 50, Comcast customers will be able to download a high-definition movie (6 GB) in about 16 minutes, a standard-definition movie (2 GB) in about five minutes and a standard-definition TV show (300 MB) in a matter of seconds.  Customers with Extreme 50 also will be able to download digital photos, songs and games faster than ever.

In addition to the new speed tiers, Comcast will soon be increasing speeds for its existing customers.

• Performance tier customers will benefit from doubled downstream and upstream speeds, offering up to 12 Mbps and 2 Mbps, respectively.

New Business Class Tiers
Business customers will benefit from wideband with increased efficiency and productivity.  Customers can sign up for the Deluxe 50 Mbps / 10 Mbps tier for $189.95/month, which includes a full suite of features and support.   As part of their service, Comcast Business Class customers receive Microsoft Communication Services, providing corporate-class e-mail, calendaring and document sharing, as well as additional benefits such as firewall protection, static IP addresses, multiple e-mail addresses and business class 24/7 customer support.   Existing business class customers also will receive complimentary speed increases – speeds on the Starter tier will be doubled to up to 12 Mbps / 2 Mbps and a new Premium Tier also will be introduced, offering speeds up to 22 Mbps / 5 Mbps for only $99.95/month.
