Hollywood blacklist

The Hollywood blacklist was the mid-20th century banning of suspected Communists from working in the United States entertainment industry. The blacklist began at the onset of the Cold War and Red Scare, and affected entertainment production in Hollywood, New York, and elsewhere. Actors, screenwriters, directors, musicians, and other professionals were barred from employment based on their present or past membership in, alleged membership in, or perceived sympathy with the Communist Party USA (CPUSA), or on the basis of their refusal to assist Congressional or FBI investigations into the Party's activities. Even during the period of its strictest enforcement from the late 1940s to late 1950s, the blacklist was rarely made explicit nor was it easily verifiable.
