Execs have thought about the idea. But Time Warner CEO Jeff Bewkes told analysts this morning that the concept of creating a subscription-based channel featuring productions from Warner Bros and HBO “is not ready for primetime.” He left the door slightly ajar, though, adding that “I don’t want to rule it out, exactly.” The problem is that his company’s shows appeal to lots of different audiences. “Comedies are different than dramas. It doesn’t make sense for us to have an all-genre network…[People] go to the Food Network expecting something different than TBS.” Besides, Time Warner already has a thriving business supplying the broadcast networks — it has at least two shows on every major one — as well as existing streaming services led by Netflix and Amazon. “We think that the better way to play it,” Bewkes says.
