The Broadcast Center is also the production base for CBS News Radio. The network's Master Control (aka Central Control) on the first floor also serves as the routing center for other programming distributed by Westwood One (formerly Dial Global). The radio network's flagship station WCBS (AM) was housed in the Broadcast Center from 2000 (moving from Black Rock, CBS's corporate headquarters at 51 West 52nd Street) until 2011 when it relocated to 345 Hudson Street in lower Manhattan, billed on-air as "The CBS Hudson Square Broadcast Center."
