when were smartphones invented

The first smartphone was invented in 1992 by IBM. It was called the IBM Simon Personal Communicator and was made available for purchase in 1994. This device combined mobile phone functionality with features like a touchscreen, the ability to send and receive emails, and built-in applications such as a calendar, address book, and appointment scheduler. The term "smartphone" became more commonly used in the 2000s, and the first widely influential smartphone was the Apple iPhone, introduced in 2007.
