1-2-3 was almost immediately successful, and by 1984, "InfoWorld" wrote that sales of VisiCalc were "rapidly declining", stating, that it was "the first successful software product to have gone through a complete life cycle, from conception in 1978 to introduction in 1979 to peak success in 1982 to decline in 1983 to a probable death according to industry insiders in 1984." The magazine added, that the company was slow to upgrade the software, only releasing an Advanced Version of VisiCalc for Apple II in 1983, and announcing one for the IBM PC in 1984. By 1985, VisiCorp was insolvent. Lotus Development acquired Software Arts, and ended sales of the application.
