David Letterman is throwing some subtle shade at his former network in the wake of its decision to cancel 'The Late Show With Stephen Colbert.'

David Letterman is subtly showing support for his successor Stephen Colbert after CBS' shock cancellation of "The Late Show."

Current “Late” host Stephen Colbert announced the end of the talk show institution last week, seeming entirely caught by surprise. Letterman helmed the series from 1993 until his retirement in 2015. He responded to the news on Monday, sharing a 20-minute supercut of bits taking potshots at the Tiffany Network.
