In the late 1990s, Twin Galaxies, which tracks video game world record scores, visited used game auctions and counted how many times the average Pac Man machine had been played. Based on those findings and the total number of machines that were manufactured, the organization said it believed the game had been played more than 10 billion times in the 20th century.
Despite the success of his game, Iwatani never received much attention. Rumors emerged that the unknown creator of Pac-Man had left the industry when he received only a $3500 bonus for creating the highest-grossing video game of all time.
It would go on to become arguably the most famous video game of all time, with the arcade game alone taking in more than a billion dollars, and one study estimated that it had been played more than 10 billion times during the twentieth century.
