Comcast Boosts Business Class Internet Speeds to 16 Mbps at no Additional Cost for Small-and Medium-Sized Companies Nationwide

PHILADELPHIA, PA - April 29, 2008 - Comcast Corporation (Nasdaq: CMCSK, CMCSA), the nation's leading provider of entertainment, information and communications, today announced that it has increased speeds for its Business Class Internet service tiers at no additional cost for Comcast Business Class Internet customers across the country. With download speeds up to 16 Mbps and upload speeds up to 2 Mbps, Comcast Business Class gives customers an ultra-fast broadband connection that's more than ten times faster than standard 1.5 Mbps DSL and the phone companies T-1 lines.

With Comcast's Business Class Internet, business customers are able to download a 220 MB file in less than 2 minutes. By comparison, downloading one 220 MB file would take 10 minutes with a 3.0 Mbps DSL connection. Downloading files gets even faster with Comcast's patent-pending PowerBoost™ Internet speed enhancer, which provides extra bursts of speed when businesses need it most to download files such as a Software Service Pack, Digital X-Rays, or a PowerPoint presentation. Uploading files are also twice as fast with the increased Internet speeds.

"Comcast is dedicated to and focused on offering a better broadband Internet experience so business customers are equipped with technology solutions that save time, increase productivity and offer more value," said Bill Stemper, President, Comcast Business Services. "We will continue to innovate to keep small- and medium-sized businesses on the cutting edge of new technology."

The new speed enhancements come soon after the launch of the Business Class Bundle, where for the first time, business owners have the opportunity to bundle their high-speed Internet service with digital voice and industry-leading video service. Additionally, Comcast business customers are backed by around-the-clock customer support which enables business owners to focus on core business initiatives. Comcast's technical support representatives are certified in all major operating systems and specialize in providing support for business solutions. Comcast also provides on-site professional service installation every time to minimize downtime when switching from another provider.

In addition, Comcast is the only major U.S. Internet service provider to make Microsoft Communications Services available at no additional cost with its broadband services, allowing the sophistication of a large enterprise communications infrastructure with fully synced e-mail, shared calendars, contacts and tasks. With Microsoft Communication Services from Comcast, small-business owners can focus on running their businesses rather than worrying about IT issues.

Comcast will continue to increase Internet speeds as it evolves from broadband to wideband with the introduction of DOCSIS 3.0 (Data Over Cable Service Interface Specifications) technology, which will set a new standard for high-speed Internet service across fiber-optic cable networks.
