Initially, available content will focus on news, sports and current events like segment clips from NBC's Today Show and FOX Sports Live, but the catalogue will continue to expand as programmers look to super-serve their viewers by integrating even more extras, bonus and complimentary series.

Initial content will come from A&E, ABC News, AMC, American Heroes, Animal Planet, BBC America, Big Ten Networks, CNBC, Cooking Channel, Destination America, Discovery, Discovery Life, DIY, E!, ESPN, Esquire Network, Food Network, Fox Business, Fox News, Fox Sports, FYI, HGTV, History, IFC, Investigation Discovery, Lifetime, LMN, MSNBC, Music Choice, NBC, NBC News, OWN, Science Channel, Sundance TV, TLC, Travel Channel, Velocity and WE TV. This programming will be delivered over the Internet to X1 and feature in the Web section of Xfinity On Demand. All of it can also be found on Xfinity.com.

"Integrating our Web content into a highly engaged platform like Xfinity On Demand on X1 is a fantastic opportunity to reach and engage millions of viewers on the best screen in the home," said Ron Lamprecht, EVP, digital distribution for NBCUniversal. "With access to platforms like X1, we are able to offer live, on demand and Web content around our properties and provide unique, branded experiences for our viewers."

The news comes as Comcast's Xfinity On Demand has reached the three billon hours viewed each year milestone. Comcast has released some usage numbers for its pay-TV home platform. It also said that while 70% of all Xfinity TV customers use Xfinity On Demand every month, that figure jumps to 85% among X1 users. And, in addition to traditional programming on the TV, the average person is also spending nearly an hour viewing online video every day.

"Today, there is arguably more high quality programming available than ever before, with the average person watching four to five hours of live or time-shifted TV each day," said Matt Strauss, EVP and GM, Video Services, Comcast Cable, in a blog. "In this golden age of TV, we're focused on providing platforms and experiences for our customers to watch what they want, when and where they want."
