This is by far the most engaging and probably the most extensive study on tablet advertising ever put together. The full report can be found only on tablets – search for ‘The Pool – Tablet Lane’. But if you are after ad-formats only, the link below is what you need.
The gist of it is that 3 of the best performing ad formats are Rich Media Interstitials, Banner-to-Full Page Rich Media and Pre-Roll Overlay and the study also tells you in what sort of content environment they work best.
Kudos to Vivaki and team for putting this fantastic piece of work.
