John Oliver, Jon Stewart, Jimmy Fallon, Seth Meyers and more had cameos during the July 21 episode of "The Late Show With Stephen Colbert."

David Letterman and his YouTube channel uploaded a 20-minute anti-CBS compilation following Stephen Colbert's 'Late Show' cancellation.

Stephen Colbert spoofed that viral Coldplay concert clip with help from several fellow late-night hosts, plus Lin-Manuel Miranda and Weird Al.

Colbert began the episode criticizing Paramount for its decision. “How can it be a purely financial decision if The Late Show is No. 1 in ratings?” he asked. “A lot of people are asking that question.

Monday night's (July 21) show also featured kiss cam-style pop-ins from supportive fellow talkers Anderson Cooper, Jimmy Fallon, Jon Stewart and Adam Sandler.

After CBS said it was canceling "The Late Show," people online claimed its host announced a new show in collaboration with MSNBC host Rachel Maddow.

“Love you Stephen,” Severance actor Adam Scott wrote in the comments of Colbert’s Instagram clip. “This is absolute bullshit, and I for one am looking forward to the next 10 months of shows.” Jon Batiste, the show’s former bandleader, called Colbert “The greatest to ever do it,” via Instagram comments.
