First jukebox installed

In 1889, the first jukebox was installed when an entrepreneur named Louis Glass and his business associate, William S. Arnold, placed a coin-operated Edison cylinder phonograph in the Palais Royale Saloon in San Francisco. The machine, an Edison Class M Electric Phonograph with oak cabinet, had been fitted locally in San Francisco with a coin mechanism invented and soon patented by Glass and Arnold. This was before the time of vacuum tubes, so there was no amplification. For a nickel a play, a patron could listen using one of four listening tubes. Known as “Nickel-in-the-Slot,” the machine was an instant success, earning over $1000 in less than six months.[Image: From U.S. Patent No. 428,750 "coin actuated attachment for phonographs" issued to Glass and Arnold on 27 May 1890]
