Baseball fans and news junkies in Massachusetts and most of New Hampshire will now be able to watch TBS and CNN in HD from Comcast. 

With the Major League Baseball playoffs slated to start on Wednesday, TBS will carry 27 potential games in both the American and National leagues in HD, along with TBS’ regular lineup, with the new launches by Comcast. CNN’s news and political coverage of the presidential primaries will also be served up in HD mode by Comcast.

“We are committed to providing the best HD programming on the market,” said Randy Waddell, senior vice president of sales and marketing for Comcast’s North Central Division, in a statement. “The addition of TBS HD and CNN HD, combined with our already extensive HD lineup and more than 150 hours of HD On Demand content, delivers our customers the ultimate viewing experience.”

The number of HD channels an operator carries has been a bragging point between cable, satellite and telco video providers. Comcast is also facing a stiff challenge from Verizon in Massachusetts as the telco rolls out its video FiOS service.
