Sinclair Spectrum

The Spectrum was among the first mainstream-audience home computers in the UK, similar in significance to the Commodore 64 in the USA.  The introduction of the ZX Spectrum led to a boom in companies producing software and hardware for the machine, the effects of which are still seen; some credit it as the machine which launched the UK IT industry.  Licensing deals and clones followed, and earned Clive Sinclair a knighthood for “services to British industry”.
