CBS Columbia Square, located at 6121 Sunset Boulevard in Hollywood, Los Angeles, California, was the home of CBS's Los Angeles radio and television operations from 1938 until 2007. The building housed the CBS Radio Network's West Coast facilities, as well as CBS's original Los Angeles radio stations, KNX and KCBS-FM. KNXT-TV, Channel 2 (now KCBS-TV) moved into the complex in 1960, and the CBS Television Network's West Coast operations were based there until it moved to the larger CBS Television City in November 1952. After its purchase by CBS in 2002, KCAL-TV moved to the Square from studios adjacent to CBS's then-corporate sibling Paramount Pictures. Between 2004 and 2007 all of these operations moved to other facilities in the Los Angeles area.
