What was the world's first video game?

The world's first video game is considered to be "Tennis for Two." Created in 1958 by physicist William Higinbotham, the game was designed as a demonstration for visitors at the Brookhaven National Laboratory. It featured a small screen displaying a tennis court, and players could interact using analog controllers to hit a virtual tennis ball over the net. Although simple by today's standards, "Tennis for Two" laid the foundation for the development of video games and sparked the beginning of a new era in interactive entertainment.
