1970s: Solid-state electronics and digital displays introduced
The introduction of microprocessors brought pinball into the realm of electronic gaming. The electromechanical relays and scoring reels that drove games in the 1950s and 1960s were replaced in the 1970s with circuit boards and digital displays. The first solid-state pinball is believed to be Micro Games' Spirit of 76 (1976),[6] though the first mainstream solid-state game was Williams' Hot Tip (1977). This new technology led to a boom for Williams and Bally, who attracted more players with games featuring more complex rules, digital sound effects, and speech.
The video game boom of the 1980s signaled the end of the boom for pinball. Arcades replaced rows of pinball machines with video games like 1978's Space Invaders, 1979's Asteroids, 1980's Pac-Man, and 1981's Galaga. These earned significantly greater profits than the pinball machines of the day, while simultaneously requiring less maintenance. Bally, Williams, and Gottlieb continued to make pinball machines, while they also manufactured video games in much higher numbers. Many of the larger companies were acquired by, or merged with, other companies. Chicago Coin was purchased by the Stern family, who brought the company into the digital era as Stern Enterprises, which closed its doors in the mid-1980s. Bally exited the pinball business in 1988 and sold their assets to Williams, who subsequently used the Bally trademark from then on for about half of their pinball releases.
While the video game craze of the late 1970s and early 1980s dealt a severe blow to pinball revenue, it did spark the creative talents within the industry. All companies involved tried to take advantage of the new solid state technology to improve player appeal of pinball and win back former players from video games. Some of this creativity resulted in landmark designs and features still present today. Some of these include speech, such as Williams' Gorgar; ramps for the ball to travel around, such as Williams' Space Shuttle; "multiball", used on Williams' Firepower; multi-level games like Gottlieb's Black Hole and Williams' Black Knight; and blinking chase lights, as used on Bally's Xenon. Although these novel features did not win back players as the manufacturers had hoped, they changed players' perception of pinball for coming decades.
