Happy Sunday (Korean: 해피 선데이 ) is a Korean reality-variety show shown on the KBS2 network, which competes directly against MBC's "Sunday Night" and SBS's "Good Sunday" line-up.
 Although it has been broadcast since 2003, its line-up of shows has frequently changed, with a complete revamp occurring in Spring of 2007.
 At that time, three new shows were introduced – "Are You Ready", "High-Five", and "Immortal Songs".
 Due to its poor reception, "Are You Ready" quickly evolved into "1 Night 2 Days", with most of its cast intact.
 In late November 2008, "Happy Sunday" had a revamp of its shows keeping "1 Night 2 Days" as the second segment and bringing back "Immortal Songs" which was previously liked by viewers.
 However in late March, "Immortal Songs" ended once again and was replaced with "Qualifications of Men", making "Happy Sunday" an all-male cast, with a total of 14 members.
 In 2013, "Qualifications of Men" was cancelled and replaced with "Star Family Show Mamma Mia".
 On November 3, 2013 "Star Family Show Mamma Mia" was moved to Wednesday nights and replaced with "The Return of Superman".
