"What's Happening!!" is an American sitcom television series that aired on ABC from August 5, 1976, to April 28, 1979, premiering as a summer series. With good ratings and reviews, and after the failure of several other series on the network, "What's Happening!!" returned as a weekly series from November 1976 until its April 1979 conclusion; ratings were modest. "What's Happening!!" was loosely based on the Eric Monte-penned film "Cooley High". From 1985 to 1988, a sequel series titled "What's Happening Now!!" aired in first-run syndication, with most of the major cast members reprising their roles.
