Sunday Night is the longest-running South Korean television entertainment programme airing on MBC. It runs for 175 minutes, including roughly fifteen minutes of advertising. Previously named Big March of Sunday Night when it debuted in 1981, and changing its name to Sunday Sunday Night in 1988, in March 2011, the show has changed its name for the second time in its history in an effort to increase its popularity again at the 5:20PM timeslot, with its rival contenders, KBS2's Happy Sunday and SBS's Good Sunday. As of April 29, 2012, the name was once again changed to its most commonly known abbreviation, Sunday Night..
