Stephen Colbert's "Late Show" ended its nearly 11-year run last night. Colbert was joined by his mentor Jon Stewart, host of "The Daily Show," and by his TV friends John Oliver, Seth Meyers and Jimmy Fallon and Jimmy Kimmel. Colbert also sang with his surprise guest, former Beatle Paul McCartney. Finally, through visual effects, Colbert’s show and the entire theater were sucked into a giant interdimensional wormhole.   CBS canceled the show last summer, calling it a "purely a financial decision,” but the cancellation came as CBS’ parent company, Paramount Global, was seeking FCC approval for an $8.4 billion merger with Skydance Media. Colbert’s friends and fans claimed he was canceled for his continuous criticism of President Trump and his administration, which continued throughout his final months on the air.   Check out NPR News Now wherever you listen to podcasts for more of today’s news.
