During the 1920s, John D. Rockefeller Jr. had conceived the site of the current Rockefeller Center as a location for the Metropolitan Opera, but these plans were shelved and the plans eventually evolved into a mass media complex, leading to the construction of Rockefeller Center. The complex's flagship RCA Building (now 30 Rockefeller Plaza) opened in May 1933. Shortly after the RCA Building's opening, there were plans to use the space above the 64th floor as a public "amusement center". That section of the building had several terraces, which could be used to construct a dance floor, observatory, restaurant, and landscaped terrace gardens. Frank W. Darling quit his job as head of Rye's Playland in order to direct the programming for the proposed amusement space.
