Good Sunday (Korean: 일요일이 좋다) was a highly competitive and popular South Korean reality-variety show that aired on the SBS network from March 28, 2004, until March 19, 2017. Known for its format comprising multiple "corner programs" or segments, the show consistently battled rival programs on MBC and KBS2, often securing the #1 position on Sunday evening charts. Its most iconic and longest-running segment was Running Man, which premiered on July 11, 2010, and notably marked a return to the Good Sunday lineup for beloved host Yoo Jae-suk. The program ultimately concluded its run as SBS opted to transition to airing individual programs split into two parts for commercial breaks, a broadcasting practice previously not permitted for terrestrial television shows.
