General Magic was an American software and electronics company co-founded by Bill Atkinson, Andy Hertzfeld, and Marc Porat. Based in Mountain View, California, the company developed precursors to "USB, software modems, small touchscreens, touchscreen controller ICs, ASICs, multimedia email, networked games, streaming TV, and early e-commerce notions." General Magic's main product was Magic Cap, the operating system used in 1994 by the Motorola Envoy and Sony's Magic Link PDA. It also introduced the programming language Telescript. After announcing it would cease operations in 2002, it was liquidated in 2004 with Paul Allen purchasing most of its patents.
