In 1980, construction was completed on an expansion of what is now named Hartsfield–Jackson Atlanta International Airport (ATL). The busiest and most efficient airport in the world, it accommodates more than a hundred million passengers annually. Employing more than 60,000 people, the airport became a major engine for economic growth. With the advantages of cheap real estate, low taxes, right-to-work laws and a regulatory environment limiting government interference, the Atlanta metropolitan area became a national center of finance, insurance, technology, manufacturing, real estate, logistics, and transportation companies, as well as the film, convention, and trade show businesses. As a testament to the city's growing international profile, in 1990 the International Olympic Committee selected Atlanta as the site of the 1996 Summer Olympics. Taking advantage of Atlanta's status as a transportation hub, in 1991 UPS established its headquarters in the suburb of Sandy Springs. In 1992, construction finished on Bank of America Plaza, the tallest building in the U.S. outside of New York or Chicago.
