Is Pong the oldest video game

Pong is not the oldest video game.

The earliest video games predate Pong. For example, "Tennis for Two" was created in 1958 by physicist William Higinbotham. It was displayed on an oscilloscope and allowed two players to control paddles to hit a virtual ball back and forth, similar in concept to Pong but much simpler and using different technology. Another early example is "Spacewar!" developed in 1962 at the Massachusetts Institute of Technology (MIT). It was a two-player game where players maneuvered spaceships and tried to destroy each other in a space setting. 

Pong, released in 1972 by Atari, was one of the earliest commercially successful arcade video games. It popularized the concept of the video game arcade and brought video games to a wider audience, but it was not the very first video game.
