The ruling said the software giant had used its monopoly power to stifle competition and hurt consumers.
“The Court concludes that Microsoft maintained its monopoly power by anticompetitive means and attempted to monopolize the Web browser market,” Jackson wrote. “Microsoft’s anticompetitive actions trammeled the competitive process through which the computer software industry generally stimulates innovations and conduces to the optimum benefit of consumers.”
Leading up to the decision, Microsoft stock was hit hard in market trading. At the markets’ close, Microsoft stock was selling at 90 1/2, down 15 dollars from last Friday.
The Department of Justice said it welcomed the court’s decision.
“The decision will benefit consumers and stimulate competition and innovation in the high-tech industry,” Asst. Attorney General Joel Klein said in a statement.
