When Were Video Games Invented? A Timeline of the Medium's Early Evolution

There's no single "invention date" for video games—the medium emerged through decades of experimentation across academic, military, and commercial spheres. Here's a milestone-driven timeline:

Pre-Commercial Foundations (1940s–1960s)

• 1947 – Cathode-Ray Tube Amusement Device (Goldsmith & Mann). Analog missile simulator. Patent only; never built.
• 1950 – Bertie the Brain (Josef Kates). Tic-tac-toe on a 4-meter-tall vacuum-tube computer at Canadian National Exhibition.
• 1951 – Nimrod (Ferranti). Nim-playing computer for Festival of Britain. First digital game designed for public exhibition.
• 1952 – OXO (Alexander Douglas). Tic-tac-toe on EDSAC at Cambridge. First graphical display on a CRT.
• 1958 – Tennis for Two (William Higinbotham). Oscilloscope-based tennis sim at Brookhaven National Lab. Two-player, side-view, physics-based. Widely cited as the first *video game* for entertainment.
• 1962 – Spacewar! (MIT, Steve Russell et al.). PDP-1 mainframe. Two ships, gravity star, hyperspace. First influential, widely distributed (DECus tape) computer game. Inspired Nolan Bushnell.

Commercial Birth (1970s)

• 1971 – Computer Space (Nolan Bushnell/Ted Dabney, Nutting Associates). First *commercially sold* arcade game. Fiberglass cabinet, Spacewar!-inspired. ~1,500 units; too complex for bars.
• 1972 – Pong (Atari). First *mass-market* arcade hit. Simple, intuitive, profitable. ~35,000 cabinets. Launched the arcade industry.
• 1972 – Magnavox Odyssey ships. First home console.

Why "Invention" Is the Wrong Frame

Video games aren't a lightbulb—they're a convergence of display tech, real-time computing, interactive design, and commercial distribution. Each milestone above contributed a necessary piece. Higinbotham made it *playful*; Russell made it *viral*; Bushnell made it *profitable*; Baer made it *domestic*.

If forced to pick one "birth moment," 1958's Tennis for Two best fits "first video game made purely for fun on a video display." But the industry begins with Pong (1972).
