History: New York City, 1978, United States

Real estate is a major force in the city's economy, as the total value of all New York City property was $802.4 billion in 2006. The Time Warner Center is the property with the highest-listed market value in the city, at $1.1 billion in 2006. New York City is home to some of the nation's—and the world's—most valuable real estate. 450 Park Avenue was sold on July 2, 2007 for $510 million, about $1,589 per square foot ($17,104/m²), breaking the barely month-old record for an American office building of $1,476 per square foot ($15,887/m²) set in the June 2007 sale of 660 Madison Avenue.
The city's television and film industry is the second largest in the country after Hollywood. Creative industries such as new media, advertising, fashion, design and architecture account for a growing share of employment, with New York City possessing a strong competitive advantage in these industries.
High-tech industries like biotechnology, software development, game design, and internet services are also growing, bolstered by the city's position at the terminus of several transatlantic fiber optic trunk lines. Other important sectors include medical research and technology, non-profit institutions, and universities.
Manufacturing accounts for a large but declining share of employment. Garments, chemicals, metal products, processed foods, and furniture are some of the principal products. The food-processing industry is the most stable major manufacturing sector in the city. Food making is a $5 billion industry that employs more than 19,000 residents. Chocolate is New York City's leading specialty-food export, with $234 million worth of exports each year.
