David Letterman has announced he will retire as host of the Late Show in 2015. Letterman made the announcement during a taping of his show at the Ed Sullivan Theater in New York City on Thursday. Letterman had been a staple of late-night TV since Late Night with David Letterman debuted in 1982 on NBC. He headed over to CBS with the Late Show in 1993, after losing his bid to take over the Tonight Show to Leno, who retired earlier this year to make way for Fallon. He has since hosted over 4,000 episodes spanning 21 critically acclaimed seasons. Having supported music’s biggest names as well as newer, up-and-coming artists, Letterman invited the likes of Jay Z, Adele, Radiohead, Paul McCartney, Janelle Monae, Lorde, Gorillaz, and many more to his show. It remains to be seen if Letterman is abandoning the tv industry for good, possible names for his replacement at CBS include The Daily Show’s Jon Stewart and former Late Night host Conan O’Brien.
