'''Sinclair Research Ltd''' is a British consumer electronics company founded by [[Clive Sinclair]] in [[Cambridge]] in the 1970s. In 1980, the company entered the [[home computer]] market with the [[ZX80]] at £99.95, at that time the cheapest personal computer for sale in the United Kingdom. A year later, the [[ZX81]] became available through retailers, introducing home computing to a generation, with more that 1.5 million sold. In 1982 the [[ZX Spectrum]] was released, becoming the UK's best selling computer, and competing aggressively against [[Commodore International|Commodore]] and [[Amstrad]].

A combination of the failures of the [[Sinclair QL]] computer and the [[TV80]] pocket television led to financial difficulties in 1985, and a year later Sinclair sold the rights to its computer products and brand name to Amstrad. Sinclair Research Ltd continued to exist as a one-man company, marketing Clive Sinclair's inventions.
