The first incarnation of the spin-off was broadcast in 2008 by NBC as part of a block of summer reality series it branded as All-American Summer. The current version, outside the one-season summer format on NBC, has aired as a summer series on ABC since 2015, as a part of that network's 'Summer Fun & Games' blocks of primetime game shows. Like the primetime All-Star Specials aired during the late 1970s and early 1980s by the show's then-network home ABC, the episodes feature celebrities and their real families, or teams of celebrities playing as a 'family' for charity, rather than the regular format of ordinary families playing for cash and prizes. Celebrity Family Feud is a broadcast network spin-off of the syndicated American game show Family Feud.
