After many failed negotiations between Google and Yahoo, Google finally reached an agreement with Yahoo to serve its Adsense and Google AdMob for mobile on Yahoo’s network. [Here is the official announcement]
“we’re excited to announce that we recently signed a global, non-exclusive agreement with Google to display ads on various Yahoo! properties and certain co-branded sites using Google’s AdSense for Content and Google’s AdMob services.”
“By adding Google to our list of world-class contextual ads partners, we’ll be able to expand our network, which means we can serve users with ads that are even more meaningful,” Yahoo said in a statement.”
Last year, the two companies went though lengthy negotiations about a more involved ad agreement but those talks didn’t materialized. Since then, Yahoo CEO Ross Levinsohn was replaced by Marissa Mayer and she hired former Google ad executive Henrique De Castro as her chief operating officer.
So what will happen to Microsoft? Well, it is unknown at this point but Yahoo has a long term deal with Microsoft to handle its search ad business. Mayer has publicly discussed her disappointment with the way that alliance has worked for Yahoo.
