Here's a timeline of key events:
* October 1947: The House Un-American Activities Committee (HUAC) held hearings in Hollywood, investigating alleged communist infiltration in the film industry.
* October 21, 1947: Ten Hollywood writers and directors (known as the "Hollywood Ten") refused to answer questions about their political affiliations, citing their First Amendment rights.
* November 1947: The "Hollywood Ten" were found guilty of contempt of Congress and sentenced to prison.
* 1947-1950: The film industry created a "blacklist" of suspected communists and those who refused to cooperate with HUAC. These individuals were effectively barred from working in Hollywood.
* 1950s: The blacklist continued to grow, fueled by fear of communism and McCarthyism.
The blacklist gradually declined in the late 1950s and early 1960s. However, its impact on Hollywood and the lives of those affected was significant.
