Certainly, it's a big deal on CBS, which is currently marking the occasion with a 20+ hour live countdown of special moments from the show on TikTok; bits in CBS primetime tonight featuring Corden announcing the start of shows like Young Sheldon and Ghosts; a 10:00 p.m. primetime special built around his popular Carpool Karaoke segment/series and a final episode of the show at 12:37 a.m. featuring Harry Styles and Will Ferrell as his last guests. Unlike David Letterman or Conan O'Brien, Corden leaves late night as an entertainer who may not be that beloved by fans of late night TV and who didn't really change the game much – despite creating some of the most popular segments-turned-TV shows in recent TV history.
