NBC‘s The Tonight Show Starring Jimmy Fallon will join ABC’s Jimmy Kimmel Live!, CBS’ Late Show With Stephen Colbert and NBC’s Late Night With Seth Meyers in scaling back to four nights of originals a week starting this season. The move is believed to be driven by cost-cutting, which also was behind the decision to drop Late Night’s house band earlier this summer. The Tonight Show had been airing original episodes Monday-Friday during the regular season, doing two tapings on Thursday, while switching to Monday-Thursday first-run shows during the summer. The off-season schedule will now carry over to the rest of the year.
