IBM dominated the mainframe market in the 1960s through superior sales and marketing efforts rather than technical superiority. IBM spent millions on advertising and marketing campaigns to create an image of superiority, leading to the mantra "Nobody ever got fired for buying IBM." By 1985-1986, IBM's annual revenue from healthcare alone was about equal to the combined total of its next six competitors. While the System/360 mainframe was hyped for its technical capabilities, IBM's real advantage came from aggressive pricing, sales, and marketing that drove its dominance until antitrust issues in the early 1990s.
