TELCOMP was a programming language developed at Bolt, Beranek and Newman (BBN) in about 1964 and in use until at least 1974. BBN offered TELCOMP as a paid service, with first revenue in October 1965. The service was sold to a company called On-Line Systems in 1972. In the United Kingdom, TELCOMP was offered by Time Sharing, Ltd, a partnership between BBN and an entrepreneur named Richard Evans.
