After development of PONG finished in 1972, Nolan Bushnell and Allan Alcorn decided to test the arcade game out at a local watering hole that they frequented and knew the manager of; Andy Capp's Tavern.
Shortly thereafter, Bushnell went on a business trip to Chicago. While gone, the manager of the tavern called Alcorn up and said, as the story goes, "come down here and fix this f-ing thing!" Alcorn hurried down to the tavern and began to inspect the PONG cabinet, which had ceased working. Upon removing the coin mechanism, he found it to be overflowing with quarters.
From that day on, PONG fever swept the nation. The cabinet was literally jammed with quarters (and I bet many of them still had silver in them) due to the incredible popularity of it.
