Comcast Completes Launch of Extreme 50 Mbps High-Speed Internet Service in City of Philadelphia and Region

Introduces Two New, Faster Speed Tier Options and Doubles Speeds for Most Existing Customers at No Additional Cost Also Announces Having Reached Nearly 50% of the National Roll Out of Superfast Wideband Services or Nearly 25 Million Homes and Businesses

PHILADELPHIA, July 22 -- Comcast, 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 City of Philadelphia. The launch in the city completes the company's roll-out of faster Internet speeds to all areas of the Philadelphia market including the counties of Bucks, Chester, Delaware and Montgomery, southern New Jersey and northern Delaware. The speed upgrades began in December 2008.

The Company also announced it has reached nearly 50% of all homes passed by its High-Speed Internet service with its superfast wideband speeds, which means today nearly 25 million homes and businesses can now enjoy one of the fastest Internet services in the country.

With wideband, Comcast introduces a new echelon of Internet speed tiers, which redefines the customer experience online and creates a platform for Internet innovation in the years ahead. Wideband allows Comcast to offer among the fastest speeds available today, including the Extreme 50 tier with download speeds of up to 50 Mbps. It also enables Comcast to double speeds for the majority of existing high-speed Internet customers at no additional cost.

"I applaud Comcast and their efforts to be the first to bring the benefits of advanced wideband Internet to all areas of our city," said Philadelphia Mayor Michael A. Nutter. "We are proud of hometown companies like Comcast that enrich our lives through their innovation and investment."

"Wideband utilizes our existing advanced fiber-optic network in neighborhoods across our footprint. With this next generation service, our customers' online experience is dramatically enhanced," said Amy Smith, senior vice president of Comcast's Freedom Region. "This new service will enable us to continue to offer our customers even faster speeds and an entirely new realm of Internet innovation."

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.

  --  Ultra, offering up to 22 Mbps of downstream speed and up to 5 Mbps of
      upstream speed.

With Extreme 50, Comcast customers will be able to download a high-def movie (6 GB) in about 16 minutes, a standard-def movie (2 GB) in about 5 minutes and a standard-def 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 also is increasing speeds for most of its existing customers.

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

  --  Performance Plus customers will be upgraded to Comcast's Blast! tier,
      which will double their download speeds to up to 16 Mbps and provide
      up to 2 Mbps of upload speed.

Plus, with PowerBoost technology, customers are able to enjoy even faster speeds to download and upload files such as videos, games, music and photos.

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, 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 will also be introduced, offering speeds up to 22 Mbps / 5 Mbps.
