Symantec, Metrowerks

During the 1990s, Symantec switched focus away from development of its own products and towards acquisition of other companies. An early purchase gave Symantec ownership of Norton Utilities, created in the mid-1980s by software engineer Peter Norton. At one time Symantec was also known for its development tools, particularly the THINK Pascal , THINK C, Symantec C++ , and Visual Cafe packages that were popular on the Macintosh and IBM PC compatible platforms; they exited this business in the late-1990s as competitors such as Metrowerks, Microsoft, and Borland gained significant market share.
