Conan O'Brien, the beloved late-night host, is set to make a highly anticipated return to NBC's "The Tonight Show" after more than a decade. The comedian will appear on Jimmy Fallon's show on April 9 to promote his new travel series, "Conan O'Brien Must Go," which is set to premiere on Max. O'Brien's history with "The Tonight Show" dates back to 2009 when he took over the hosting duties from Jay Leno, who had moved to a prime-time show on NBC. However, O'Brien's time as host was short-lived as NBC proposed moving his show to a later timeslot to accommodate Leno's return. This led to a public spat and O'Brien ultimately leaving NBC in 2010.

Since then, O'Brien has found success hosting his late-night show on TBS and launching his podcast, "Conan O'Brien Needs a Friend." His return to "The Tonight Show" marks a significant moment in late-night television history, showcasing a shift from intense competition between hosts to a more congenial and friendly atmosphere. O'Brien's new travel series will take him to countries like Ireland, Thailand, Argentina, and Norway, where he will visit friends he made through his podcast.

The overall vibe among late-night talk show hosts has evolved, with hosts like Fallon, Stephen Colbert, Seth Meyers, John Oliver, and Jimmy Kimmel coming together to support their staff during a writers strike. O'Brien's return to "The Tonight Show" symbolizes a reconciliation of sorts in the late-night world, as he joins Fallon on the same stage where his hosting journey began over a decade ago.
