A jukebox is a partially automated music-playing device, usually a coin-operated machine, that will play a patron's selection from self-contained media. The classic jukebox has buttons with letters and numbers on them that, when entered in combination, are used to play a specific selection.
In 1890, Louis Glass and William S. Arnold invented the nickel-in-the-slot phonograph, the first of which was an Edison Class M Electric Phonograph retrofitted with a device patented under the name of Coin Actuated Attachment for Phonograph. The music was heard via one of four listening tubes.
The term "jukebox" came into use in the United States around 1940, apparently derived from the familiar usage "juke joint", derived from the Gullah word "juke" or "joog" meaning disorderly, rowdy, or wicked.
The IBM Simon Personal Communicator was a handheld, touchscreen cellular phone and PDA designed and engineered by International Business Machines Corp. (IBM) and assembled under contract by Mitsubishi Electric Corp. BellSouth Cellular Corp. distributed the Simon Personal Communicator in the United States between August 1994 and February 1995, selling 50,000 units. The Simon Personal Communicator was the first cellular phone to include telephone and PDA features in one device.
IBM debuted a prototype device, code named "Angler," on November 23, 1992 at the COMDEX computer and technology trade show in Las Vegas,Nevada, United States. The Angler prototype combined a cell phone and PDA into one device, allowing a user to make and receive telephone calls, facsimiles, emails and cellular pages, among other functions.
BellSouth executives gave the finished product its final name, "Simon Personal Communicator", before its public debut at the Wireless World Conference in November 1993. In addition to its ability to make and receive cellular phone calls, Simon was also able to send and receive faxes, e-mails and cellular pages. Simon featured many applications including an address book, calendar, appointment scheduler, calculator, world time clock, electronic note pad, handwritten annotations and standard and predictive stylus input screen keyboards.
The Simon used the file system from Datalight ROM-DOS along with file compression from Stacker. IBM created a unique touch-screen user interface for Simon; no DOS prompt existed. This user interface software layer for Simon was known as the Navigator.
