Informatics General

Informatics General Corporation, earlier Informatics, Inc., was an American computer software company in existence from 1962 through 1985 and based in Los Angeles, California. It made a variety of software products, and was especially known for its Mark IV file management and report generation product for IBM mainframes, which became the best-selling corporate packaged software product of its time. It also ran computer service bureaus and sold turnkey systems to specific industries. By the mid-1980s Informatics had revenues of near $200 million and over 2,500 employees.

Computer historian Martin Campbell-Kelly, in his 2003 volume From Airline Reservations to Sonic the Hedgehog: A History of the Software Industry, considers Informatics to be an exemplar of the independent, middle-sized software development firms of its era, and the Computer History Museum as well as the Charles Babbage Institute at the University of Minnesota have conducted a number of oral histories of the company's key figures. Historian Jeff Yost identifies Informatics as a pioneering "system integration" company, similar to System Development Corporation. The Chicago Tribune wrote that Informatics was "long a legend in software circles".

Informatics General was acquired by Sterling Software in 1985 in what was the first hostile takeover in the software industry. Immediately, Sterling Software became a member of the largest corporations within the software industry, with $200 million in revenue.
