Tom (b. 1937) and Dick (b. 1939) Smothers attained national success as a folksong and comedy duo during the folk revival of the early 1960s. Their innovative variety show, The Smothers Brothers Comedy Hour, debuted in February 1967, mixing old and new acts and styles of comedy. Their political satires on war, religion, guns, drugs, and racism, during increasingly polarized times, antagonized CBS officials and affiliates. The series was censored and eventually cancelled in 1969.
