Psion PLC is a consumer hardware company which developed the Psion Organiser as well as a whole range of more advanced, clamshell-design Personal Digital Assistants. Psion today comprises one remaining operating division, the Canadian Psion Teklogix, having closed or disposed of all its previous operations. Although its actual operations are based in Canada, Psion itself is a British company.
1984 marked Psion's first foray into hardware; the Psion Organiser, the world's first handheld computer, in appearance resembling early games machines. In 1986 the vastly improved Psion Organiser II was released, whose success led the company into a decade long period of "Psion" Computer and operating system development. It included a simple-to-use database programming language, OPL, which sparked a large independent software market. In 1987 Psion began development of its "SIBO" ("SIxteen Bit Organiser") family of devices and its own new multitasking operating system called EPOC to run its PDA products. This development produced the Psion Series 3 (1993-1998) and the Psion MC-series laptops.
