The twelve-acre complex in midtown Manhattan known as Rockefeller Center was developed between 1929 and 1940 by John D. Rockefeller, Jr, on land leased from Columbia University.

One of the complex's first tenants was The Radio Corporation of America, hence the names "Radio City" and "Radio City Music Hall."
