The European Commission has announced that it carried out surprise inspections at the premises of a manufacturer of chips for central processing units and at a number of personal computer (PC) retail outlets. The Commission believes that these companies may have violated EC Treaty rules on restrictive business practices and/or abuse of a dominant position. Intel, one of the world’s largest chip manufacturers, confirmed that it was the manufacturer inspected. Europe’s largest PC retailers, Media Markt and DSG International, also confirmed that they had been inspected. While the Commission has declined to comment, it has been reported that the recent dawn raids of Intel and retailers represent an expansion of the Commission’s investigation into Intel’s conduct to exclude rival chip-maker, Advanced Micro Devices.
