“DelData Service”, a time-sharing system, was introduced in Denmark by ØK Data (a subsidiary of ØK, the East Asiatic Company) in August 1968. The system was originally developed by General Electric in cooperation with Dartmouth College, who also developed the programming language BASIC. The system was in operation in various US cities already from 1965 and in Denmark it continued until 1991. The users subscribed to DelData and did their programming and computations from Teletype terminals via standard telephone lines.
