The IBM Simon Personal Communicator (simply known as IBM Simon) is a handheld, touchscreen PDA designed by International Business Machines (IBM), and manufactured by Mitsubishi Electric.[6] Although the term "smartphone" was not coined until 1995, because of Simon's features and capabilities, it has been retrospectively referred to as the first true smartphone.[2][7][8][9]
BellSouth Cellular Corp. distributed the IBM Simon in the United States between August 1994 and February 1995, selling 50,000 units. The Simon Personal Communicator was the first personal digital assistant or PDA to include telephony features (make phone calls). The battery lasted only an hour, and flip phones became increasingly slim which led to its demise.[10]
