Peter Norton Computing

Peter Norton Computing, Inc., was a software company founded by Peter Norton. The first and best known software package it produced was Norton Utilities. Another successful software package was Norton Commander, especially the DOS version. In 1990, the company was acquired by Symantec. The acquired company became a division of Symantec and was renamed Peter Norton Computing Group. Most of Norton Computing's 115 employees were retained.

The Symantec merger helped Norton Computing regain the market share it was losing to competitors, especially Central Point Software. Norton Computing's revenues tripled between June 1990 and September 1991, and by November it appeared to have regained the market lead over Central Point.
