The game that existed before the game industry did.
Built by physicist William Higinbotham at Brookhaven National Laboratory in 1958, Tennis for Two displayed a side-view tennis court on an oscilloscope screen. Players used analog controllers with knobs and buttons to lob a glowing dot over a net. It was created to entertain visitors during an open house, not to launch an industry. Higinbotham never patented it, never commercialized it, and the machine was dismantled after two years. Nobody involved thought they were making history.
Example
Visitors at Brookhaven's 1958 open house lined up for hours to play Tennis for Two, ignoring the actual nuclear physics exhibits. The game was so popular that Higinbotham upgraded it the following year with a larger screen and adjustable gravity settings, letting players simulate tennis on the moon or Jupiter.
Why it matters
Tennis for Two is widely considered the first video game created purely for entertainment. It predates the entire concept of a gaming industry by over a decade and proves that the human desire to play interactive electronic games existed long before anyone figured out how to sell them.
