Google said in a blog that it has looked at how consumers engage with ads on tablets, and concludes that "they have higher expectations of ads on tablets, believing they should be more interactive and touch screen friendly."
So it's come up with Rich Media Designs for Mobile, which lets advertisers create rich media banner ads using existing assets.
And in search it has put Media Ads in beta this week. Media Ads bring video content directly into an ad on the search results page. In addition to watching video game, TV or movie trailers, US consumers will also be able to view locally relevant movie showtimes within the ad.
These new tablet-specific ad formats build on earlier launches including tablet-specific ad formats on AdMob and tablet-targeting in Adwords.
