Magic Fingers

The "Magic Fingers" motel bed coin-operated massager is a relatively unconventional vibrator from the late 1950s and early 1960s. It was produced by Magic Fingers, Inc. in Rochelle, New Jersey.

Design context
The Magic Finger vibrator was a device designed to improve the conventional vibrating beds in the 1950s. The design was fairly novel; initially beds had their vibration function built-in. However, the Magic Finger vibrator was a separate part that could be attached to any bed. This simple design of modularity was the main factor which led to the popularity of vibrating beds; within two years, over 250,000 such vibrators were installed.

Decline
As a result of being installed primarily in hotels (which charged a quarter for around 15 minutes of vibration), the devices soon began to be associated with more "seedy" motels and their popularity declined in the 1980s, around two decades after their invention.
