In the Intel case, the commission penalized the company over rebates it granted to four major computer manufacturers -- Dell Inc., Hewlett-Packard Co., NEC Corp. of Japan and Lenovo Group -- for using its microchips between 2002 and 2007. The antitrust authority found that Intel had used the rebates, coupled with its dominant position, to lock rival Advanced Micro Devices Inc. out of the market, reducing choice for consumers. The EU also said Intel made payments to electronics retailer Media Saturn Holding on the condition that it only sold computers containing Intel's microprocessors.
