Three European countries claim that Google injects editorial oversight to stifle competition. According to The Telegraph, the European Commission has launched an investigation into Google. The UK price comparison site Foundem, and French legal directory says that Google demotes sites in search rankings as they are considered a threat to their advertisement revenue. On the Google blog, Google has posted that they will provide feedback and information regarding these complaints. They also go on to say that their business operates in the interests of their users, partners and the European competition law.
This is not the first time that Google goes under investigation. Its acquisition of DoubleClick was also investigated in the USA by the FTC before it was approved. In 2008 a deal between Google and Yahoo was denied and since then Yahoo has recently signed a deal with Microsoft.
