In October 1947, 10 members of the Hollywood film industry publicly denounced the tactics employed by the House Un-American Activities Committee (HUAC), an investigative committee of the U.S. House of Representatives, during its probe of alleged communist influence in the American motion picture business. These prominent screenwriters and directors, who became known as the Hollywood Ten, received jail sentences and were banned from working for the major Hollywood studios. Their defiant stands also placed them at center stage in a national debate over the controversial anti-communist crackdown that swept through the United States in the late 1940s and early 1950s. Besides the Hollywood Ten, other members of the film industry with alleged communist ties were later banned from working for the big movie studios. The Hollywood blacklist came to an end in the 1960s.
