channel groups

Bloomberg LP has told Comcast Corp. it will file a complaint with the Federal Communications Commission unless Comcast agrees to include its Bloomberg Television channel in the news-channel groups on its cable-television systems.

The online TV services of the four major U.S. networks, ABC, CBS, NBC and Fox, along with Hulu, accounted for a combined 53 percent of the ad-supported online TV market that generated $448 million in revenues in 2008, according to a new report by Screen Digest.

The remaining share of revenues was made up of the online video services of major sports leagues, video services from traditional online portals, and direct services from other major channel groups and content owners.
