The story

Founded by Peter Norton in 1982, in Santa Monica.1

Peter Norton founded the company in 1982 with $30,000 and an IBM computer. The company was a pioneer in DOS-based utilities software. Its 1982 introduction of the Norton Utilities included Norton's UNERASE tool to retrieve erased data from DOS disks.

In 1984, Norton Computing reached $1 million in revenue, and version 3.0 of the Norton Utilities was released. Norton had three clerical people working for him. He was doing all of the software development, all of the book writing, all of the manual writing and running the business. The only thing he wasn't doing was stuffing the packages. He hired his fourth employee and first programmer, Brad Kingsbury, in July 1985. John Socha, the author of Norton Commander until 1989, was hired shortly after. From November 1985 until April 1986 Warren Woodford worked at Norton Computing and created Norton Guides. In late 1985, Norton hired a business manager to take care of the day-to-day operations.

In 1985, Norton Computing produced the Norton Editor, a programmer's text editor created by Stanley Reifel, and Norton Guides, a terminate-and-stay-resident program which showed reference information for assembly language and other IBM PC internals, but could also display other reference information compiled into the appropriate file format. Norton Commander, a file managing tool for DOS, was introduced in 1986. In this year PNCI reached $5 million in revenues with Norton Utilities still bringing the largest parts.

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.
