Question: When was the investigative committee appearing the the 1990 documentary Berkeley in the Sixties abolished?

The Interim Committee on Un-American Activities, most commonly known as the Canwell Committee, (1947-1949) was a special investigative committee of the Washington State Legislature which in 1948 investigated the influence of the Communist Party USA in Washington state.  Named after its chairman, Albert F. Canwell, the committee concentrated upon communist influence in the Washington Commonwealth Federation and its relationship to the Democratic Party in Washington, as well alleged Communist Party membership of certain faculty members at the University of Washington in Seattle. <SEP> Edward Eugene "Eugene" or "Goober" Cox (April 3, 1880 – December 24, 1952) served as a U.S. Representative from Georgia for nearly twenty-eight years.  A conservative Democrat who supported segregation and opposed President Franklin Delano Roosevelt's "New Deal," Cox became the most senior Democrat on the House Committee on Rules.  Two special investigative committees that he chaired were heavily criticized as result-oriented persecutions of those Cox did not like.  A failed attempt to create another such committee would turn out to have far-reaching consequences: in 1941, with American entry into World War II seeming inevitable, Cox proposed an investigative committee, similar to the Civil War-era Joint Committee on the Conduct of the War, to deal with matters of national defense.  When Roosevelt learned of Cox's intentions, he pre-empted them by agreeing to a similar proposal from Missouri Senator Harry S. Truman; the Truman Committee would come to be seen as a significant asset to the war effort, and its chairman - a little-known "backbencher" at the time of its founding - would become Roosevelt's Vice President and, after his death in 1945, President of the United States. <SEP> Berkeley in the Sixties is a 1990 documentary film by Mark Kitchell.  The film features 15 student activists and archival footage of Mario Savio, Todd Gitlin, Joan Baez, the Rev. Dr. Martin Luther King Jr., Huey Newton, Allen Ginsberg, Gov. Ronald Reagan and the Grateful Dead.  The film is dedicated to Fred Cody, founder of Cody's Books.  It was nominated for an Academy Award for Best Documentary Feature.  The film highlights the origins of the Free Speech Movement beginning with the May 1960 House Un-American Activities Committee hearings at San Francisco City Hall, the development of the counterculture of the 1960s in Berkeley, California, and ending with People's Park in 1969. <SEP>  The HUAC was created in 1938 to investigate alleged disloyalty and subversive activities on the part of private citizens, public employees, and those organizations suspected of having communist ties.  In 1969, the House changed the committee's name to "House Committee on Internal Security".  When the House abolished the committee in 1975, its functions were transferred to the House Judiciary Committee. The House Un-American Activities Committee (HUAC; a.k.a., House Committee on Un-American Activities, HUAC or HCUA) was an investigative committee of the United States House of Representatives.
