Flippers arrive and pinball becomes an argument about skill

What happened

Before 1947 a pinball player launched the ball and then watched. Scoring depended on where it happened to fall, which is why authorities treated the machines as gambling devices, especially once operators started paying out on high scores. Harry Mabs's design for Gottlieb added small solenoid-driven bats along the sides of the playfield, six of them, wired to buttons the player could press. The ball could now be saved, aimed and kept in motion. Later cabinets narrowed the idea down to the familiar pair at the bottom, but the change in what a player was doing happened here.

Legal consequences took decades to work out. New York City had banned the machines in the early 1940s under Mayor Fiorello La Guardia, who called them a racket that preyed on children and had confiscated machines destroyed in front of photographers. Chicago and Los Angeles imposed comparable restrictions. Skill was the industry's best answer to all of this, and the New York ban finally fell in 1976 after a hearing where the writer Roger Sharpe played a machine for the City Council. By his own account he called a shot and made it.

Both halves of that story get repeated loosely. Flippers did not appear fully formed, since the first ones faced outward and sat oddly high by modern standards, and the shift from chance to skill was gradual rather than instant. What the record supports is narrower and still important: from 1947 onward manufacturers designed around what a player could do, which handed the trade a defense it could carry into a courtroom.

The world at the time

Postwar America had loose change to spend and considerable anxiety about where teenagers were spending it. Pinball sat under a cloud in several major cities, licensed narrowly or prohibited outright, and the trade press gave ordinances as much space as new models. Manufacturers in Chicago were meanwhile adding electricity, lights, chimes and bumpers to what had been silent countertop boxes.

What it changed

Flippers turned pinball into a durable competitive hobby, with leagues and tournaments that continue today. Bans lifted gradually through the 1970s, by which point arcades were filling with video cabinets sold through the same distributors. The skill defense was reused whenever officials moved against coin-operated machines, and its logic echoes in later court fights over how games should be treated.
