Adam Sandler, Anderson Cooper, Jon Stewart and Jimmy Fallon were among those who made surprise appearances on Monday's episode after CBS announced that the late-night show would be ending in May 2026.

NEW YORK — Stephen Colbert has received support from his fellow late-night TV hosts following his cancellation by CBS, including from his predecessor. David Letterman, who was the host of “The Late Show” for 22 years, used his YouTube channel to post a video montage of the many times he ripped into CBS over the years for various reasons.

In 1993, he started working as a writer-producer on Late Night with David Letterman, which aired on NBC. Burnett ultimately made the move to CBS with Letterman when The Late Show was picked up at that network.

John Oliver has weighed in on CBS' cancellation of "The Late Show With Stephen Colbert," calling it "terrible news for the world of comedy."

The network claimed it was “purely a financial decision.” “We consider Stephen Colbert irreplaceable and will retire ‘The Late Show’ franchise in May of 2026,” CBS executives’ statement read. “We are proud that Stephen called CBS home. He and the broadcast will be remembered in the pantheon of greats that graced late night television.”
