The Metropolitan Square Corporation (the precursor to Rockefeller Center Inc.) was formed in December 1928 to oversee construction. However, the Metropolitan Opera wanted to hold out for a more favorable lease because it worried about the site's profitability. After the stock market crash of 1929, the Metropolitan Opera could not afford to move anymore, and on December 6, 1929, the plans for the new opera house were abandoned completely. In order to make a profit on the site as quickly as possible, Rockefeller devised new plans within a month so that the site could become profitable. The developers entered into talks with Radio Corporation of America (RCA) and its subsidiaries, National Broadcasting Company (NBC) and Radio-Keith-Orpheum (RKO), to build a mass media entertainment complex on the site. By May, RCA and its affiliates had made an agreement with Rockefeller Center managers to lease space and develop part of the complex.
