Which was the first video game ever made?

In October 1968, a physicist by the name of William Higginbotham made the first game. It was a tennis game. The game was put on display in the Brookhaven National Laboratory open house and was a hit! The physicist, Higginbotham, was born in 1910 and grew up in New York. He joined an instrumentation group in 1948 and in order to claim the audience attention more, he decided to invent a game.

He put together various pieces to create a tennis game. The players would hit the ball against each other by pressing a button at a specific time. The graphics were just lines displayed by a cathode ray oscilloscope and the ball was a dot.
