The 193940 New York World's Fair was a world's fair held at Flushing MeadowsCorona Park in Queens, New York, United States. It was the second-most expensive American world's fair of all time, exceeded only by St. Louis's Louisiana Purchase Exposition of 1904. Many countries around the world participated in it, and over 44 million people attended its exhibits in two seasons. It was the first exposition to be based on the future, with an opening slogan of "Dawn of a New Day", and it allowed all visitors to take a look at "the world of tomorrow".

When World War II began four months into the 1939 World's Fair, many exhibits were affected, especially those on display in the pavilions of countries under Axis occupation. After the close of the fair in 1940, many exhibits were demolished or removed, though some buildings were retained for the 19641965 New York World's Fair, held at the same site.

The National Broadcasting Company (NBC) is an American English-language commercial broadcast television and radio network which is owned by Comcast through NBCUniversal. The network’s headquarters is located at 30 Rockefeller Plaza in New York City, with additional major offices near Los Angeles (at 10 Universal City Plaza), and Chicago (at the NBC Tower). Along with ABC and CBS, NBC is one of the traditional "Big Three" American television networks. NBC is sometimes referred to as the "Peacock Network", in reference to its stylized peacock logo, introduced in 1956 to promote the company's innovations in early color broadcasting; it became a part of the network's official emblem in 1979 before being modified to its current form in 1986.

NBC has thirteen owned-and-operated stations and nearly 200 affiliates throughout the United States and its territories some of which are also available in Canada and Mexico via pay-television providers or in border areas over the air. NBC also maintains brand licensing agreements for international channels in South Korea and Germany.
