Instead of focusing only on your connection, Comcast's got a new service on deck that offers support for your laptop, gaming console, routers, and other equipment that contributes to your online experience. Xfinity Signature Support can be built into your monthly plan, or you can pay as you go. It's only available in the Twin Cities, Chattanooga, and Atlanta areas right now, but should be rolled out nationwide by the end of the year.

COMCAST INTRODUCES XFINITY SIGNATURE SUPPORT

New Technical Support and Equipment Protection Offering Helps Meet Consumers' Evolving Technology
Support Needs; Is Next Step in Company's Ongoing Focus on Enhancing the Customer Experience

PHILADELPHIA, PA – March 9, 2011 – Comcast Corporation (Nasdaq: CMCSA, CMCSK) today
announced the launch of a new 24x7 technical support and equipment protection program for the growing
number of home electronics devices – like laptops, home networking equipment, gaming consoles, Wi-
Fi enabled smart phones and tablets – people are connecting to Comcast's services. Called Xfinity
Signature Support, this service offers customers a single source for troubleshooting and support for
their computers, home networks and many other devices and is another step in the company's focus on
delivering an end-to-end exceptional customer experience backed by the Comcast Customer Guarantee.
The new offering enables customers to select an enhanced level of technical support with monthly
subscription plans and one-time support options and is offered in addition to the 24x7 support Comcast
already provides for its video, high-speed Internet and phone services.

"We want our customers to have a great experience with Comcast, and we've been making significant
investments to enhance our products while improving the service and support we deliver," said Mitch
Bowling, Senior Vice President and General Manager of New Businesses for Comcast Cable. "Given the
incredible growth and complexity of personal electronics devices, our customers have told us they would
like additional choices for technical assistance beyond the support we already provide for their video,
Internet and voice services. As we continue to invest in the overall Comcast experience, Xfinity Signature
Support lets us provide an end-to-end technical support solution for customers."

According to a 2010 survey by Parks Associates*, more than 50 percent of Americans with Internet
service look to their broadband provider as their first or second choice in solving their home computer-
related technical issues. Additionally, 75 percent of those surveyed prefer to receive all of their technical
support services from a single vendor.

With Xfinity Signature Support, Comcast customers will have access to knowledgeable and experienced
IT specialists who can provide supplementary technical support online, over the phone or in the home.
Assistance is available either as part of a monthly subscription plan or on a stand-alone basis for one-
time fixes, such as virus removal or connecting printers or game consoles to wireless networks. Xfinity
Signature Support also offers extended equipment plans covering computers and flat-panel TVs.
Comcast is initially launching Xfinity Signature Support in the Twin Cities, Atlanta and Chattanooga
markets, with plans to make it available in the remainder of the company's markets in 2011. For more

Xfinity Signature Support complements the company's overall efforts to deliver an exceptional customer
experience every day, which includes offering the Comcast Customer Guarantee, the company's promise
to hold its products, services and people to the highest standard. The Customer Guarantee is backed by
significant service enhancements focused on ensuring every customer interaction is handled right the first
time and giving customers more choice and control as well as making it easier for them to do business
with Comcast.
