No one truly recognizes who discovered the initial video game, however, it is thought to have been an individual named as William Higinbotham. Higinbotham invented a game known as Tennis for Two back in the year 1958, and this game resembles the well-known Atari game called Pong. William made this game in an cathode-ray oscilloscope to amuse visitants to his laboratory where he worked as a researcher.
