Video games have actually not been around for a long time. Children probably believe video games have been around forever because there has never been a time when video games were not around them. However, they were invented and became available in the 1970s. A version of tic tac toe was created in the 1950s though.
Some of the video games that were created prior to the 1970s were not always available to everyone. Only twenty years later did video games become accessible and cheap enough for the average person to own or play at an arcade. A tic tac toe game as a video game was created in 1950 by Josef Kates. It was created for an exhibition known as the Canadian National Exhibition.
