JukeboxIn 1890, two U.S. patents for the first jukebox were issued to Louis Glass and his business associate, William S. Arnold (No. 428,750, -1) concerning a “coin actuated attachment for phonographs.” Their first jukebox was a coin-operated Edison Class M Electric Phonograph with oak cabinet placed in the Palais Royale Saloon in San Francisco. 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 half a year. |
