NBC Studios are located in the historic 30 Rockefeller Plaza (on 49th Street, between Fifth and Sixth Avenues) in the borough of Manhattan, New York City. The building houses the NBC television network headquarters, its former parent General Electric, and NBC's flagship station WNBC (Channel 4), as well as cable news channel MSNBC. When NBC Universal relocated to New York, 24-hour cable news television network MSNBC joined the network on that day as well. The new studios/headquarters for NBC News and MSNBC are located in one area.
The first NBC Radio City Studios began operating in the early 1930s. Tours of the studios began in 1933, suspended in 2014 and resumed on October 26, 2015. Because of the preponderance of radio studios, that section of the Rockefeller Center complex became known as Radio City (and gave its name to Radio City Music Hall, a gigantic and renowned venue for theatre and films located in Radio City). Even into the present decade, tickets for shows based at 30 Rock bear the legend "Radio City".
