A company known as State of the Art, Incorporated introduced software into the market in the mid-1980s. It was called the “Master Accounting Series for the 90s” and was known, for short, as MAS 90. Like many similar companies, State of the Art, Inc. gained traction in the market with their MAS 90 software by encouraging others to become resellers. Their resellers were, at the time, most often certified public accounts (CPAs), who used the software, liked it, and then recommended it to others.
MAS 90 is no longer strictly accounting software, CPAs are no longer the ones promoting/reselling it, and State of the Art, Inc. is no longer the company supporting it.
