As the 1970 dawned, TV had become the centre of family entertainment. The '70s ushered in a new era in the type of programmes that would dominate primetime, focusing especially on relevancy, including socially relevant comedies like All In The Family, M*A*S*H, Good Times and Welcome Back, Kotter. The 70's would also see the twilight of the television variety hour, but not before some dominate shows like The Carol Burnett Show, The Sonny and Cher Comedy Hour, and Rowan and Martin's Laugh-In saw their peak in popularity. It was the golden age for TV's champions of justice with classics like Baretta, Charlie's Angels and Columbo.
