Celebrities React To Conan O'Brien Leaving Late-Night TV

It's the end of an era. The beloved comedian Conan O'Brien is leaving the late-night docket forever, after 28 years of delighting viewers with his wacky humor. O'Brien was a writer for shows like "The Simpsons" and "Saturday Night Live" before launching his own late-night TV show "Late Night with Conan O'Brien" in the '90s. He eventually went on to host "The Tonight Show" for several months before launching his latest eponymous late-night show "Conan," which recently aired its final episode.

Though fans are devastated about O'Brien's departure from late-night TV, there's still more hilarious content to come from the veteran comedian. His next venture will be a weekly variety show on HBO Max, though specifics about the series have yet to come. HBO's Chief Content Officer Casey Bloys spoke about O'Brien's new show, saying, "Conan's unique brand of energetic, relatable, and at times, absurdist, comedy has charmed late-night audiences for nearly three decades. We can't wait to see what he and the rest of Team Coco will dream up for this brand new, variety format each week" (via WarnerMedia).

Since the last episode of "Conan" aired, fans of O'Brien's have taken to social media to express their appreciation for the prolific host — including other celebrities.

If you can manage that, it's the definition of heaven on Earth."
