''Tennis for Two'' was first shown on October 18, 1958.<ref name="pioneer"/> The game environment was rendered as a horizontal line, representing the tennis court, and a short vertical line in the center, representing the tennis net as viewed edge-on. The first player would press the button on their controller to send the ball, a point of light, over the net, and it would either hit the net, reach the other side of the court, or fly out of bounds. The second player could then hit the ball back with their controller while it was on their side, either before or after it bounced on the ground.<ref name="TCW3942"/> Hundreds of visitors lined up to play the new game during its debut.<ref name="anatomy" /> Higinbotham claimed later that "the high schoolers liked it best, you couldn't pull them away from it."<ref name="Replay50s"/> Due to the game's popularity, an upgraded version was shown the following year, with enhancements including a larger screen and different levels of simulated gravity.<ref name="pioneer" /> Players could set the game to simulate the gravity levels of the Moon or Jupiter.<ref name="TCW3942"/> Higinbotham referred to the game as ''Tennis for Two'', though a placard attached to the 1959 version titled it "Computer Tennis". After the 1959 exhibition, the game was dismantled so its components could be put to other uses.<ref name="TCW3942"/>
