NBC has decided to cut back 'The Tonight Show Starring Jimmy Fallon' from five nights a week to four, with reruns airing on Friday nights. This change, effective immediately, aligns the show with its late-night competitors, such as 'The Late Show with Stephen Colbert' and 'Jimmy Kimmel Live,' all of which have four-day production schedules. The decision is part of broader cost-cutting measures at NBC, which also included firing the house band from 'Late Night with Seth Meyers.' Despite the reduction in episodes, Fallon signed a contract earlier this year to host 'The Tonight Show' through 2028. NBCUniversal Media Group chairman Mark Lazarus expressed confidence in Fallon's ability to innovate and continue entertaining audiences. The move reflects ongoing challenges in the late-night TV industry, including declining viewership and the shift towards streaming platforms.
