At one time Symantec was also known for its development tools, particularly the THINK Pascal, THINK C, Symantec C++, Enterprise Developer and Visual Cafe packages that were popular on the Macintosh and IBM PC compatible platforms. These product lines resulted from acquisitions made by the company in the late 1980s and early 1990s. These businesses and the Living Videotext acquisition were consistently unprofitable for Symantec, and these losses diverted expenditures away from both the Q&A for Windows and the TimeLine for Windows development efforts during the critical period from 1988 through 1992. Symantec exited this business in the late-1990s as competitors such as Metrowerks, Microsoft and Borland gained significant market share.
