Several companies have been accused in court of using knowingly false announcements to gain market advantage. In 1969, the United States Justice Department accused IBM of doing this in the case "". After IBM's competitor, Control Data Corporation (CDC), released a computer, IBM announced the System/360 Model 91. The announcement resulted in a significant reduction in sales of CDC's product. The Justice Department accused IBM of doing this intentionally because the System/360 Model 91 was not released until three years later. IBM avoided preannouncing products during the antitrust case, but after the case ended it resumed the practice. The company likely announced its PCjr in November 1983—four months before general availability in March 1984—to hurt sales of rival home computers during the important Christmas sales season.
