From the days of the railroad, Binghamton was a transportation crossroads and a manufacturing center, and has been known at different times for the production of cigars, shoes, and computers. IBM was founded nearby, and the flight simulator was invented in the city, leading to a notable concentration of electronics- and defense-oriented firms. This sustained economic prosperity earned Binghamton the moniker of the Valley of Opportunity. However, the job cuts defense firms made after the Cold War led the region to lose a large part of its manufacturing industry.
