 IBM dominated the electronic data processing market for most of the 20th century, initially controlling over 70 percent of the punch card and tabulating machine market and then achieving a similar share in the computer market.IBM asserted that its successes in achieving and maintaining such market share were due to its skill, industry and foresight; governments and competitors asserted that the maintenance of such large shares was at least in part due to anti-competitive acts such as unfair prices, terms and conditions, tying, product manipulations and creating FUD (Fear, Uncertainty and Doubt) in the marketplace.IBM was thus the defendant in more than twenty government and private antitrust actions during the 20th century.
