High Quality Content by WIKIPEDIA articles! 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` 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` then-corporate sibling Paramount Pictures. Between 2004 and 2007 all of these operations moved to other facilities in the Los Angeles area.
