GE Building

Extracted from the Wikipedia article 30 Rockefeller Plaza.
1980s and 1990s
Meanwhile, the Rockefeller Group had begun expanding the Rainbow Room. The observation deck closed in 1986 because the expansion cut off the only access between the observation deck and its elevators. The Rainbow Room also reopened in December 1987 after the Rockefeller Group conducted an extensive renovation. The RCA Building was renamed the GE Building in July 1988, and the signage atop the building was changed accordingly, despite concerns that it could be confused with the General Electric Building on 570 Lexington Avenue. Mitsubishi Estate, a real estate subsidiary of the Mitsubishi Group, purchased a majority stake in the Rockefeller Group in 1988, including the GE Building and Rockefeller Center's other structures. Despite the renaming, 30 Rockefeller Plaza continued to be popularly known as the RCA Building. Subsequently, Rockefeller Center transferred some of the unused air rights above the British Empire Building and La Maison Francaise to the Rockefeller Plaza West skyscraper on Seventh Avenue. In exchange, the Rockefeller Group had to preserve the original buildings between 49th and 50th Streets under a more stringent set of regulations than the rest of the complex. While the GE Building's air rights were unaffected, the structure fell under the new regulations.
