The Newton is a specified standard and series of personal digital assistants (PDAs) developed and marketed by Apple Computer, Inc. from 1993 to 1998. An early device in the PDA category – the term itself originating with the Newton – it was the first to feature handwriting recognition. Newton devices run on a proprietary operating system, Newton OS; unlike the company's Macintosh computers, Apple licensed the software to third-parties, who released Newton devices alongside Apple's own MessagePad line.
Apple started developing the platform in 1987; conceptualized by Steve Sakoman as a tablet-like device with handwriting capabilities, he worked with AT&T Corporation to develop a low-power processor, Hobbit, for the project.
