Comcast Offers the Fastest Residential Internet Service to the Most Homes in the U.S.

Comcast Corporation (Nasdaq: CMCSA, CMCSK), one of the nation's leading providers of entertainment, information and communication products and services, announced today that its newest ultra-fast Xfinity Internet speed tier, Extreme 105, is now available to more than 40 million homes in major markets across the nation including San Francisco, Seattle, Portland, Denver, Chicago, Miami, Washington, D.C., Philadelphia, and the majority of Boston, among others.

"This speed tier continues to expand our portfolio of Internet service offerings and takes them up to a whole new level," said Cathy Avgiris, Senior Vice President and General Manager of Communications and Data Services. "With it, we're powering the digital home of the future, where entire families using multiple devices - laptops, gaming consoles, tablets, smartphones - can all take advantage of high-bandwidth applications simultaneously ensuring they each have a great online experience." 

The Extreme 105 Mbps service, which also offers up to 10 Mbps upload speeds, is available for new or existing customers at an introductory rate of $105 per month for 12 months as part of their Triple Play bundle. In addition, the service comes with a wireless home networking gateway that turns an entire house into its own WiFi hotspot. Comcast offers Extreme 105 service on a standalone basis, and also offers a variety of other speed tiers in either bundles or as standalone packages, so there's something for everyone and consumers can choose a service that best meets their needs. 

Extreme 105 is made possible through the use of DOCSIS 3.0 technology. At a connection speed of up to 105 Mbps, Comcast customers can not only download and watch a hi-def movie in about 5 minutes, but also play online interactive games, send and receive email attachments, shop, and update social networking Web pages faster than ever before.

Here are some examples that compare different online customer experiences of a 105 Mbps connection to a 6 Mbps service:
