Red Channels: The Report of Communist Influence in Radio and Television was an anti-Communist tract published in the United States at the height of the Red Scare. Issued by the right-wing journal Counterattack on June 22, 1950, the pamphlet-style book names 151 actors, writers, musicians, broadcast journalists, and others in the context of purported Communist manipulation of the entertainment industry. Some of the 151 were already being denied employment because of their political beliefs, history, or association with suspected subversives. Red Channels effectively placed the rest on the industry blacklist.
"[S]everal commercially sponsored dramatic series are used as sounding boards, particularly with reference to current issues in which the Party is critically interested: "academic freedom", "civil rights", "peace", the H-bomb, etc.... With radios in most American homes and with approximately 5 million TV sets in use, the Cominform and the Communist Party USA now rely more on radio and TV than on the press and motion pictures as "belts" to transmit pro-Sovietism to the American public."
No cause which seems calculated to arouse support among people in show business is ignored: the overthrow of the Franco dictatorship, the fight against anti-Semitism and Jimcrow, civil rights, world peace, the outlawing of the H-Bomb, are all used. Around such pretended objectives, the hard core of Party organizers gather a swarm of "reliables" and well-intentioned "liberals", to exploit their names and their energies.
