Another reason why Jimmy Fallon's late night future seems fairly safe is that he's also invested in a pair of NBC's current and upcoming unscripted primetime offerings. He's an executive producer on the recently debuted and Martin Short-hosted game show Password, where he'll also be part of the celebrity panels.

Greg Gutfeld made his broadcast late-night debut on “The Tonight Show Starring Jimmy Fallon” Thursday evening, marking a rare network crossover with the Fox News host visiting NBC’s 30 Rock. A conservative media personality is a rare booking for “The Tonight Show” and the 10-minute segment between Gutfeld and Fallon largely steered clear of politics.

After Stephen Colbert announced "The Late Show" was being canceled by CBS, fellow late-night hosts Jon Stewart, John Oliver, Jimmy Fallon, Seth Meyers, plus other hosts and comedians, showed up to support him.
