30 Rockefeller Plaza

30 Rockefeller Plaza is a skyscraper that forms the centerpiece of Rockefeller Center in the Midtown Manhattan neighborhood of New York City, United States. Completed in 1933, the 66-story, 850 ft (260 m) building was designed in the Art Deco style by Raymond Hood, Rockefeller Center's lead architect. 30 Rockefeller Plaza was known for its main tenant, the Radio Corporation of America (RCA), from its opening in 1933 until 1988 and then for General Electric until 2015, when it was renamed for its current owner, Comcast. The building also houses the headquarters and New York studios of television network NBC; the headquarters is sometimes called 30 Rock, a nickname that inspired the NBC sitcom of the same name. The tallest structure in Rockefeller Center, the building is the 28th tallest in New York City and the 65th tallest in the United States, and was the third tallest building in the world when it opened.
