Nasdaq's founding (1971)
Nasdaq launched as the world's first fully electronic stock market, replacing phone calls and floor shouts with a price-quoting computer network. Stock exchanges had worked the same way for two centuries.
Electronic trading won out over floor-based markets across the globe within two decades.
The exchanges that built the new rails kept control; those that resisted lost share or were bought.
Nasdaq itself was the disruptive new rail. Now it is trying to build the next one so blockchain trading doesn't bypass it the way electronic trading bypassed floor markets.
