TV hosts and celebrities are reacting to news of the cancellation of "The Late Show with Stephen Colbert" and the entire franchise.

Stephen Colbert was receiving messages of support and affection from his fellow late-night hosts after announcing that CBS was canceling his show, “The Late Show With Stephen Colbert,” next May.

The end of the 'Late Show' franchise is a major blow for a once-beloved TV format, which has lost relevance and advertising dollars.
