Profs and All-in-1, as well as integration with Harvard Graphics.Though SPC's earliest product was for the Apple II personal computer, most of its products were for use on text-based DOS desktop computers, with non- graphical-user-interfaces (GUI), long before the graphical GUIs of Macintosh or Microsoft Windows existed.

Software Publishing Corporation ( SPC) was a Mountain View, California-based manufacturer of business software, originally well known for its 'pfs:' series (and its subsequent 'pfs:First' and 'pfs:Professional' derivative series) of business software products, it was ultimately best known for its pioneering Harvard Graphics business and presentation graphics program.Harvard Graphics, from Software Publishing Corporation and initially called Harvard Presentation Graphics, is a graphing/plotting/presentation creation.Lany 1991 es presenta el Harvard Graphics per Windows 3.0.

With the advent of the IBM PC the following year, though, the company quickly shifted focus to the burgeoning DOS-based desktop computer market, which also included a fast-growing number of IBM PC-compatible computers. The first application to be launched was the 'Personal Filing System' (PFS), a simple database program for Apple II computers. As MS-DOS began to disappear, so did SPC's revenues.SPC was established in 1980 by three former Hewlett-Packard employees, Fred Gibbons, Janelle Bedke, and John Page, with an eye to producing packaged software for personal computers like the Apple II. SPC scrambled to develop a Windows version of Harvard Graphics, but big competitors and their Windows-native business and presentation graphics tools had so penetrated the Windows market by then that it was just too little, too late. Windows incorporated built-in graphical capabilities, so much of what Harvard Graphics provided was no longer needed. This factor played a role in the company's ultimate demise in 1996, as Microsoft Windows was shipping on most desktop computers.

It was the first of a family of products released by SPC under the 'pfs:' brand which, when installed onto the same computer, combined to form a sort of office suite which included companion products pfs:Write (a word processor), pfs:Plan (a spreadsheet), pfs:Report ( reporting software), and pfs:Graph ( business graphics software). Major products SPC's first product, its 'PFS' brand database for Apple II computers, was reworked, improved, and then released as pfs:File, a flat-file database for DOS. By only a year later, in 1985 SPC company had achieved $50 million in revenue from the IBM deal, alone. IBM advertised the suite using a Chaplin-esque figure getting all of his ducks in a row, in a Super Bowl TV ad, and in print ads. In 1984 IBM executed an OEM-style agreement pursuant to which SPC would develop the IBM Assistant Series, which was an only slightly enhanced, but completely rebranded version of the 'pfs:' family of products (described in the next section) such that no mention of SPC was present in the software or its documentation and which IBM intended to sell with its IBM PC and PCjr computers.

Lighter-weight versions of the core 'pfs:' word processing, database, spreadsheet and data communications programs were released as a single, integrated suite called pfs:First Choice for DOS, intended to directly compete with, but be more economical than, Microsoft Works for DOS. While relatively limited in their capabilities compared with better-known and more powerful products like the DOS database dBase III, the DOS spreadsheet Lotus 1-2-3, and the DOS word processor WordPerfect, the trio of SPC products proved popular, because of their simplicity and ease-of-use, with beginning and intermediate DOS PC users. Eventually, SPC offered a low- to mid-level desktop publishing product called pfs:Publisher and it packaged the core word processing, database and spreadsheet products into a suite named pfs:Office.

When all three were installed on the same machine, the separately-purchased products could interact with one another as a sort of office suite. Starting with the second versions of the Professional trio, the 'pfs:' was dropped from the product names, making them, simply, Professional Write, Professional File, and Professional Plan. These became SPC's higher-end, truly business-oriented and, eventually, networkable and multi-user software product line. There was no compatibility between the 'pfs:First' series and the 'pfs:' series.In response to business users' requests for a far more powerful, yet still economical word processor that really could compete with the likes of the better-known and more-popular DOS word processors like WordPerfect (and even, by then, Microsoft Word for DOS, SPC released an enhanced version of pfs:Write called pfs:Professional Write, a much higher-powered word processor which was eventually joined by companion products pfs:Professional File (a more powerful database, to better compete with dBase), and pfs:Professional Plan (a more powerful spreadsheet, to better compete with Lotus 1-2-3). A business graphics package called pfs:First Graphics came next, so that the 'pfs:First' series could have lightweight business graphics like the original, and slightly heavier-weight, 'pfs:' series offered.

This move made SPC an essentially one-product company. As the popularity of Harvard Graphics soared, SPC shifted focus to high-end business graphics software, and so it sold the 'pfs:' and related series software to Spinnaker Software in 1991. There was, however, no compatibility of the trio, or the Harvard series products, with any of SPC's other earlier 'pfs:' or 'pfs:First' products.Starting with the second versions of the Professional Write, Professional File and Professional Plan trio, a separately-purchased Professional series networking add-on (available in 5-user, 10-user and larger packs) could be obtained so that they could all function in a multi-user local area networking (LAN) environment utilizing rudimentary file locking (but not record locking) via NetBIOS on such as Novell's NetWare, or Banyan VINES.In 1986, SPC released its groundbreaking Harvard Presentation Graphics, one of the first PC applications which allowed users to combine charts, clip art, and text and display fonts into presentation slides.The power of Harvard Graphics product made it extremely popular with DOS PC users, helping to drive SPC's sales revenues to $150 million by 1990.

In 1996 SPC was purchased by, and became a subsidiary of, Allegro New Media, Inc., a New Jersey-based multimedia publisher of interactive CD-ROM software applications, including 25 titles in five product lines, the most notable of which were its Entrepreneur Guides, Berlitz Executive Travel Guides, Learn To Do Series and Business Reference Series. So as DOS desktop computers began to disappear from US businesses by 1994, and revenues from the DOS-based version of Harvard Graphics disappeared with them, SPC's overall revenues plummeted.In 1994, the firm laid off half its staff and Gibbons stepped down as chief executive.
