By the mid-to-late 1970s, viewers tired of socially responsible sitcoms. Former CBS head of programming Fred Silverman defected to struggling ABC started the trend of TV centred on sexual gratification and bawdy humor and situations, nicknamed "jiggle television." Jiggle TV shows included the crime-fighting television series "Charlie's Angels", which starred up-and-coming sex symbols Farrah Fawcett, Jaclyn Smith, and Kate Jackson and the risqué sitcom such as "Three's Company", modeled after the British series "Man About the House", in which swinging single-man Robin Trip pretended to be gay in order to live in an apartment with two single women. Mildly controversial at the time, the show quickly became a Top Ten hit in the ratings.
