We knew it was only a matter of time before the Godzilla-sized Google got in on the in-game advertising game. And now they have. Adsense for Games is a go.

While the industry has only seen about $1 billion experts expect Google’s entry into the field to springboard it to new heights. With Google’s acquistion of Adscape Media last year and the ensuing beta program they are confident that they are on the right track. Game developers like Konami, Playfish and Zynga participated in the beta, but now other developers and publishers will also be able to apply to the program.

Google is making strategic partnerships with other companies to gain access to their ad channels. The first of which is Mochi Media, which serves in-game ads to 60 million people. They are granting Google access to 5,000 games which they are already serving to in order to push the European launch of AdSense for Games.

Over 25% of Internet users play online games every week, which is over 200 million users worldwide. Beta users of AdSense for Games can display video ads, image ads, or text ads within your online games to earn revenue. At this time, eligible publishers must have a minimum of 500,000 game plays and have 80% of their traffic from the U.S. or the U.K.
