Live television broadcast of weekly National Football League (NFL) games
Monday Night Football (often abbreviated as MNF) is the branding used for broadcasts of National Football League (NFL) games that air on Monday nights. It originally ran on ABC from 1970 to 2005, before moving exclusively to sister network ESPN from 2006 to 2019. While still airing on ESPN, MNF returned to ABC in 2020 beginning with select ESPN simulcasts, later expanding to select ABC exclusive telecasts in 2022, and since 2023 ABC has aired the bulk of the games in simulcast with ESPN.
