The European Commission (Commission) has launched an in-depth investigation into Google’s proposed takeover of the online advertising technology company, DoubleClick. Google is an Internet search engine that provides facilities for online advertising, both on its own websites and also on partner websites, through its network ‘AdSense’. DoubleClick is active in the ad serving, management and reporting technology sectors that ensure that adverts are published on appropriate websites. The technology also allows publishers and advertisers to monitor the performance of their advertisements. The Commission is to investigate whether in the absence of the merger, DoubleClick would have become an effective competitor to Google. It is also concerned that, as a result of the merger, there could be a reduction in competition in the advertising space and intermediation services and the ad serving technology markets. The Commission’s final decision will be published by 2 April 2008.
