A couple of updates for the display advertising space.
On the advertising end, AdWords Display Ad Builder now offers InVideo creation. An InVideo ad is a Flash overlay that plays at the bottom of a video a user is watching. These ads are used on YouTube vids.
On the publisher side, the ability to let multiple Google-certified ad networks to compete for ads on your site has been extended. Initially, it was launched to just North America and Europe. Now, the option is available globally.
