00:00 Pinball machines have a long history, dating back to the 19th century with the introduction of the ball shooter mechanism.

04:57 In the 1930s, there was a surge in pinball machine innovation, including the introduction of coin operation, back glass, electric current, legs, tilt mechanism, bumpers, sounds, scorekeeping, and most importantly, flippers, which fundamentally changed pinball from a game of chance to a game of skill.

09:45 Pinball was illegal in most major cities in the United States from the 1940s to the mid-1970s because it was considered a game of chance and associated with gambling.

14:21 Pinball was banned in most major cities in the US until the mid-1970s, but people still played it and manufacturers continued to innovate; it also became a symbol of rebellious youth and was considered a game of skill rather than chance.

18:41 Pinball had its golden age between 1948 and 1958, but declined in popularity with the rise of video games in the 90s, leaving only a few major pinball machine producers, until the company Stern became the sole manufacturer of pinball machines.

23:34 Pinball had experienced a decline in popularity, but recently there has been a resurgence with the emergence of new pinball manufacturers and an increase in home sales of pinball machines.

28:42 Pinball scoring involves propelling the ball and using bumpers and ramps to score points, with the goal of keeping the ball from going down the drain, and as players get better, they can learn combinations and tricks to score more points; the ball is steel, weighs about 2.8 ounces, and can reach speeds up to 90 miles an hour, and there are also ceramic pinballs called power balls that are lighter and faster and immune to magnets; the game also includes a black box that houses the electronics and solid state components, and the back glass serves as an advertisement and provides information and hints to players; solid state electronics took over the back glass, while the rest of the machine remains electromechanical.

33:08 Pinball machines are still electromechanical, with about a half a mile of wiring, and the play field is tilted and made of wood, although newer machines have replaced the wood with plasma or LCD screens; when starting a game, a ball falls into the launch lane and can be launched either manually with a plunger or automatically with a solenoid, which is advantageous because it allows for more balls to be sent into action during gameplay.

37:49 Pinball machines often have hidden games within the game, such as playing poker on the back glass, and earning a "Wizard Award" allows players to enter a special round with flooded balls and bumper hits worth hundreds of thousands of points.

42:14 Pinball machines have a "match" feature where players can win a free game if the last two digits of their score match a random number flashed by the computer, and tilting the machine too far can result in warnings and eventually losing the ball.

46:33 A doctor explains that sometimes patients bring in lint and hair follicles thinking it's an infection, but it's important to treat the root cause of their symptoms regardless.
