# 1973 in video games

"none" is preferred when the title is sufficiently descriptive; see [[WP:SDNONE]]
The year 1973 saw a substantial increase in the number of video games created and distributed. In coin-operated games, a craze for Pong-style games ignited the first fad for video games both in the United States and other countries such as Japan and the United Kingdom. Time-sharing networks saw greater proliferation of popular programs through type-in listings. The PLATO computer located at the University of Illinois Urbana-Champaign played host to some of the earliest massively multiplayer games.
