Silicon Alley is an area of high tech companies centered around southern Manhattan's Flatiron district in New York City.[1] The term was coined in the 1990s during the dot-com boom, alluding to California's Silicon Valley tech center. The term has grown somewhat obsolete since 2003 as New York tech companies spread outside of Manhattan, and New York as a whole is now a top-tier global high technology hub.[2] Silicon Alley, once a metonym for the sphere encompassing the metropolitan region's high technology industries,[3] is no longer a relevant moniker as the city's tech environment has expanded dramatically both in location and in its scope. New York City's current tech sphere encompasses a universal array of applications involving artificial intelligence, the internet, new media, financial technology (fintech) and cryptocurrency, biotechnology, game design, and other fields within information technology that are supported by its entrepreneurship ecosystem and venture capital investments.
