Datotek
Also known as AT&T Datotek

Datotek, or Datotek Inc., was a manufacturer of cryptographic solutions, based in Dallas (Texas, USA). The company was established in 1969 by D.R. Whitson and specialised in voice encryption systems (scramblers) and later also in digital message encryptors. Under the direction of John H. Nugent, the company grew to a major player in the cryptographic industry, and by the time they were taken over by AT&T in 1989, they had an estimated market share of approx. 30% [1].


After the takeover by AT&T, Datotek went on as an independent wholly-owned subsidary of AT&T, under the name AT&T Datotek. In 1994, AT&T Datotek had a revenue of US$ 7.5 million [2]. In June 1995, AT&T sold the company to arch rival Technical Communications Corporations (TCC), for the relatively low sum of US$ 4,069,000, and the name Datotek disappeared.
