Seems a remote possibly but just in case some of you still use Yahoo nowadays, just don't be surprised to see a Google-sponsored ad on Yahoo's web pages.

Some time last year the techno world was abuzz with rumors of a supposed nexus between social media giant Google and the waning Yahoo. It was controversial in the sense that Google's arch nemesis - Microsoft had already cut a search deal in 2009 with Yahoo.

Adding a new dimension to the changing alliances in the social media industry, Yahoo today announced officially that it has 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".
