Silicon Alley refers to the technology and startup ecosystem located in New York City. It is known for its concentration of tech companies, entrepreneurs, and venture capitalists. The term is often used to describe the area in and around Manhattan, particularly in neighborhoods like Chelsea and SoHo, where many digital and tech firms have established their offices. The name is a play on Silicon Valley, the famous tech hub in California. Silicon Alley has grown significantly since the late 1990s, becoming a vibrant center for innovation in areas such as software development, e-commerce, and media technology.
