In 1972, as a newbie at the young game-maker Atari, Alcorn was asked by company cofounder Nolan Bushnell to make a simple ping pong game under a contract with General Electric. Although the contract didn’t really exist, Alcorn worked hard nonetheless to make something good. Three months later, the first coin-operated Pong machine was installed at Andy Capp’s Tavern in Sunnyvale, CA — and became an instant hit. As Bushnell would later say, it was “so simple that any drunk in any bar could play.” Alcorn designed both the arcade and home versions, and Pong’s popularity sparked the globally ubiquitous, multi-billion-dollar game industry we know today. “It wasn’t my intention. I’m just as surprised as the next guy,” he told the Computer History Museum in 2011. After Atari, his crucial involvement with many Silicon Valley startups earned him an Apple Fellowship; his own company, Zowie Intertainment, was acquired by LEGO in 2000. Alcorn continues to remain involved in tech’s fun side through Hack the Future, which offers daylong “hackfests” to school-age kids that teach them programming and connect them to mentors.
