About National Video Games Day
Most video game historians believe that National Video Game Day dates back to the year 1991. According to Frank Cifaldi of the Video Game History Foundation, the first written account of a National Video Game Day can be found in a 1991 calendar of events from Chase. This calendar lists July 8th as National Video Game Day and claimed that it was sponsored by one David Earle. Not much is known about Earle except that he was supposedly the president of the Kid Video Warriors organization.
In recent years, Chase still shows Video Game Day but it has mysteriously moved to September 12th.
The Chase description says National Video Games is "A day for kids who love video games to celebrate the fun they have playing them and to thank their parents for all the consoles, games and quarters they have provided to indulge this enthusiasm."
