The company moved to its new headquarters from longterm lease space at 485 Madison Avenue at 52nd Street. Prior to the building's completion, CBS moved its radio network studios—the CBS News network radio studios on the 17th floor of 485 Madison and other studios across the street in the CBS Studio Building—to the CBS Broadcast Center on 57th Street starting in 1964. The TV news studios, based mostly at the Graybar Building near Grand Central Terminal, also moved to the Broadcast Center around that time, starting with the "CBS Evening News" studio-newsroom in 1963.
