International Computers and Tabulators (generally referred to by the acronym, ICT) was a British computer company, originally formed from the merger of two punched-card equipment companies, British Tabulating Machine (BTM) and Powers-Samas, in 1959. It operated from then until 1968, absorbing GEC, EMI Electronics and Ferranti in the process, as a wave of mergers consolidated the British computer industry. It merged with English Electric Computers (EEC) in 1968, to form ICL.
