AdMeld, a real time bidding platform (RTB) and an advertising start up, has been acquired by Google for $400 million. The New York based Admeld, launched in 2007, provides advertising optimization platform services for web publishers.
Google had planned to acquire AdMeld in February 2011 for $200 million, but the offer was turned down by AdMeld as the price was too low.
AdMeld has yet to make an announcement about the acquisition.
