CBS Columbia Square

CBS Columbia Square (formerly known as the KCBS-TV/FM and KNX Studios) is a group of radio and television studios located at 6121 Sunset Boulevard in Hollywood, California. Since 1938, the television and radio stations KCBS-TV, KCBS-FM and KNX-AM have had many of their studios there, and added the operations of independent station KCAL-TV in 2002. The CBS Television Network built a new studio facility to handle its larger production needs, and its Television City opened in November 1952. The CBS Radio Network's West Coast operations still remained at Columbia Square.

KCBS-TV and KCAL-TV are scheduled to move into a new building at CBS Studio Center in Studio City in 2006, while KCBS-FM and KNX signed-on from their new studios in the Miracle Mile neighborhood on L.A.'s Wilshire Boulevard on August 14, 2005. KNX conducted a farewell broadcast from its Columbia Square studio on that night.
