Despite the East Coast roots of technology entrepreneurship and venture capital (VC), by the 1990s Silicon Valley had gained a major advantage over the Cambridge-Boston area. In 1995 Silicon Valley’s share of all VC investments in the U.S. stood at 22.6%, more than twice New England’s 9.9% share. It is less well-known that Silicon Valley’s share of U.S. venture capital has skyrocketed since then, unaffected by wide fluctuations in the total pool of VC investments during this period. With an almost 50% share, the Bay Area now towers over New England, whose share has stayed put at around 10%.
