A look at Comcast's holdings:
The division touts itself as the nation's largest provider of video, high-speed Internet and telephone services to residential customers under the XFINITY brand. It also provides similar services to businesses and sells advertising.
As of Dec. 31, the company had 53.1 million video, high-speed Internet and phone service customers, representing a 3 percent increase over the same day the year before.
The company said Thursday that it currently has 22 million pay TV subscribers, but plans to divest 3 million of them once the deal for Time Warner Cable Inc. closes. With the addition of Time Warner Cable's 11.2 million subscribers, the combined entity will end up with about 30 million.
