The buttons actually began appearing in AdWords search ads in late May. The move to display was announced in September, with the idea that you or your friends in your Google network can show that you like or want to recommend a display ad.
"As we explained in our initial announcement several weeks ago, we believe that incorporating personal recommendations into display ads has the potential to change the way people view advertising," Dan Friedman, AdWords product marketing manager, wrote on the company's Inside AdWords Blog. "A display ad becomes much more powerful when people can see which of their friends and contacts have chosen to endorse it."
The idea is similar to that of Digg's "Diggable" banner ads and Facebook's "Like"-able banners, both of which run within those companies' networks.
