Google has announced, via its Adwords blog, that it is rolling out the +1 button onto advertisements which appear on the Google Display Network.
This means that advertisements which have been +1′d (I’ve no idea if that’s the right past tense phrase for +1) by your friends will show up more often on pages you view (if they are part of the Google Display Network and you are logged into your Google account). Additionally the advert will also have their picture in the corner, highlighting their personal recommendation.
How many people are actually likely to +1 an advertisement isn’t a point discussed in Google’s blog post.
