The State of New York has brought a lawsuit against world's largest manufacturer of computer microprocessor- Intel, following a two-year investigation into its competitor practices. The New York Attorney General, Andrew Cuomo said, Intel used illegal threats and collusion to maintain its 80 per cent market in computer chips. The allegations include payments given to computer manufacturers for installing only Intel processors in their products which, lawsuit says shut out rival chip makers.Earlier in the year, a fine amounting to one and a half billion dollars was imposed on the company by regulators in Europe after similar allegations. The Company says, its payments were within the rules and did not harm consumers.
