30 Rockefeller Plaza is an American Art Deco skyscraper that forms the centerpiece of Rockefeller Center in Midtown Manhattan, New York City. Formerly called the RCA Building from 1933 to 1988, and later the GE Building from 1988 to 2015, it was renamed the Comcast Building in 2015, following the transfer of ownership to new corporate owner Comcast. Its name is often shortened to 30 Rock.
The building is most famous for housing the headquarters and New York studios of television network NBC, as well as the Rainbow Room restaurant. At 850 feet high, the 66-story building is the 14th tallest in New York City and the 47th tallest in the United States. It stands 400 feet shorter than the Empire State Building. 30 Rockefeller Center underwent a $170 million floor-by-floor interior renovation in 2014.
