Conan had The Tonight Show for about a year, but early in 2010 NBC management wanted to take Jay Leno off of his fledging primetime program and put him back on the late night schedule. This did not sit well with Conan, as he did not want The Tonight Show to be delayed into airing early the next morning, just so Jay Leno could have a 30 minute program starting at 11:35 p.m. Eastern and Pacific time. Hence, there was a parting of the ways between Conan and NBC and Jay Leno ended up back at The Tonight Show.
The Flaming C
The Flaming C was a hero modeled after Conan O'Brien's appearance. It was designed by Bruce Timm. Flaming C has made cameo appearances on Young Justice. Even had a whole animated skit dedicated towards the character. Recently, the character has even been shown as a Superman skin in the game, during one of Conan's Clueless Gamer where he was playing Injustice Gods Among Us. Flaming C was shown fighting Aquaman in the game.
Conan has cameo'd as himself in the video game Lego Batman 3: Beyond Gotham.
