AOL has continued its spending spree in the online marketing sector with the purchase of German internet advertising management company Adtech.
The Time Warner company has bought a controlling stake in the Frankfurt-based company – which serves publishers in over 25 countries – for an undisclosed fee, Reuters reports.
Following yesterday’s announcement that it has acquired Third Screen Media for a similarly undisclosed sum, the move represents a significant drive on the part of AOL to strengthen its search engine marketing profile.
AOL describes Boston-based Third Screen Media as a "leading mobile advertising network and mobile ad-serving and management platform provider".
In recent weeks, Google has acquired DoubleClick for $3.1 billion (£1.6 billion), while Yahoo! bought Right Media for a sum of around $680 million.
Meanwhile, Microsoft is reported to be considering bids for 24/7 Real Media and Yahoo!.
