FierceCable: Comcast is growing its pay-TV base again. “We have more video customers today than we did a year ago,” said CEO Brian Roberts, speaking at the Morgan Stanley Media, Technology and Telecom Conference. Despite adding 89,000 pay-TV customers in the fourth quarter, Comcast finished 2015 about 36,000 video subs in the red, while both Time Warner Cable and Charter reported narrow gains.
