Rowan & Martin's Laugh-In(1968)
Rowan & Martin's Laugh-In is an American sketch comedy television program that ran for 140 episodes from January 22, 1968, to March 12, 1973, on the NBC television network. It was hosted by comedians Dan Rowan and Dick Martin and featured, at various times, Chelsea Brown, Johnny Brown, Ruth Buzzi, Judy Carne, Richard Dawson, Henry Gibson, Teresa Graves, Goldie Hawn, Arte Johnson, Larry Hovis, Jeremy Lloyd, Dave Madden, Pigmeat Markham, Gary Owens, Pamela Rodgers, Barbara Sharma, Alan Sues, Lily Tomlin and Jo Anne Worley.
Laugh-In originally aired as a one-time special on September 9, 1967 and was such a success that it was brought back as a series, replacing The Man from U.N.C.L.E. on Mondays at 8 pm. The title of the show was a play on the "love-ins" or "be-ins" of the 1960s hippie culture, terms that were, in turn, derived from "sit-ins", common in protests associated with civil rights and anti-war demonstrations of the time.
In 2002, Rowan & Martin's Laugh-In was ranked #42 on TV Guide's 50 Greatest TV Shows of All Time.
