50 Rockefeller Plaza

[2] Rockefeller Center's executives went into talks with the Associated Press for a building on the northern empty lot,[3] which was occupied by the complex's truck delivery ramp.

[7] In January 1938, Associated Press agreed to rent the fourth through seventh floors of the structure, with the building to be named for the company.

[10] The building, located at 50 Rockefeller Plaza, was built to the outer limits of its lot without any setbacks or rooftop gardens; it rose only 15 floors because of the 1916 zoning law and the paucity of other tenants.

[3][7] The presence of Associated Press and Time Inc. expanded Rockefeller Center's scope from strictly a radio-communications complex to a hub of both radio and print media.

The lobby received black-terrazzo floors with brass detail; several pieces of artwork; curved limestone walls; and bronzed-steel urns.
