Philadelphia, PA.

Comcast Also Increasing e-mail Storage to 1.7GB

Comcast brings speed to the market.

Today the company officially announced a 4Mbps speed tier as a new option for its High-Speed Internet service. This announcement comes within a year of Comcast doubling customer downstream speed to 3Mbps, at no additional cost - and establishing an industry benchmark.

Comcast High-Speed Internet customers now can choose between two high- speed options: 4Mbps and 3Mbps. Combined with Comcast's world-class content and built-for-broadband applications, these two speed tiers empower users to enjoy the broadband experience that is best for them and their families. The new 4Mbps option is particularly ideal for households engaged in numerous high-speed-enabled activities, such as: streaming audio; multi-player and online gaming; large file downloads; and networking.

Upon selecting their speed, customers can then choose between standard High-Speed Internet service (one connection) or Comcast Home Networking (up to five devices), now available on both speed tiers, at no additional monthly service cost. The 3Mbps and 4Mbps services are available for $42.95 and $52.95* per month, respectively, for current cable television customers. [Prices may vary slightly by market.]

The new "4Meg" (4Mbps) speed tier will be available to all Comcast High- Speed Internet customers by September, when it is expected to be rolled out system-wide. Comcast 4Meg is already available in a number of Comcast markets, including: Baltimore, Boston, Chicago, Philadelphia, and Washington, D.C.

"Our guiding principle is to maximize the value that our customers receive from their Comcast High-Speed Internet connection. Speed is a critical component, but overall value can only be measured when you consider speed in relation to what that speed enables," stated Greg Butz, senior vice president of marketing & business development for Comcast Online. "At Comcast, we are continuously working to improve every aspect of the broadband Internet experience: speed; network performance; content and content management and services; security; and customer support."

Increased E-mail Storage

Comcast is further enhancing its service offering this summer by upping its e-mail storage capacity. The Comcast High-Speed Internet service provides up to seven (7) e-mail accounts - and Comcast will increase the storage capacity of each account from 10MB to 250MB. That means a total increased capacity potential of 1.75GB, as compared to the previous 70MB. In addition, customers can enjoy nearly unlimited storage for their digital photos through the Comcast Photo Center.
