Stephen Colbert was unafraid to call out CBS and Paramount after The Late Show was abruptly axed, but according to an insider, his pals are concerned he’s going too far with his continued criticism of the networks.

It’s impossible to ignore the effect that stalwart TV comedians like Johnny Carson, David Letterman, Conan O’Brien and more have had on younger generations of comedians and writers. Oliver voiced his hope for that cycle of influence to continue on, even if it won’t be the same.

David Letterman didn't hold back in calling out Paramount for acting out of "cowardice" in canceling his former CBS program, "The Late Show."
