AOL bought major stake in Adtech AG

In my previous post I jotted chain of reactions where major Search engine giants and leading publisher acquired major ad technology and ad network companies, following it is another BIG WWW and it is none other than AOL.Infact its a little late news(May17th) which I came across today, so I thought should pen down few infos which I have gathered.

AOL has bought major controllable stake in a german based Ad technology company "Adtech AG" however its financial transactions were not disclosed.

This action is to strengthen AOL's Ad network "Advertising.com" .This buy would give AOL's "Advertising.com" access to Adtech AG ad server "Helios IQ" . Also, before acquiring "Adtech AG", AOL has also acquired Mobile Ad network "Third Screen Media"

So who is in talks with
Eyeblaster, Tangozebra, valueclick, ..........?
