Automated phone solicitation, i.e. robocalling, was one of the earliest applications proposed for the first microcomputers. The first documented mention of it was in the "Memo from the Publisher" by David Bunnell in Personal Computing magazine, May/June 1977. Under the heading "Personal Computing Abused", Bunnell described a presentation at the World Altair Computer Convention in March, 1976 of "an intriguing business application for personal computing".
