This is a comedy program that aired every Sunday evening on KBS 2TV from May 14, 1987, to April 21, 1991. Along with "Humor No. 1 on Saturdays" at the time, it led the golden age of KBS comedy programs. The direction was initially handled by PD Yoon In-seop, then taken over by PD Kim Young-ryeol in August 1990, and changed again to PD Im Kang-ho on December 8 of the same year. It was re-broadcast on KBS Satellite 2 and Comedy TV in the early 2000s, and since 2019, KBS has been regularly uploading past videos on its YouTube channel "Kekeke TV". (Full list) Unfortunately, due to KBS's poor archive preservation status, many of the 1980s broadcasts have been lost. In particular, "Show! Video Jockey" is the predecessor program to "Gag Concert".
