Google has launched its AdSense video ads in three new-size formats, a move coinciding with the first anniversary of the service.
The click-to-play blocks pay cost-per-thousand publishers for every ad impression, regardless of video plays.
The new formats are a banner-like 728×90 “Leaderboard”, a 120×600 “Skyscraper” and a 160-x600 “Wide Skyscraper”, adding to the previous inventory of four sizes.
Clicking on a play button that appears in a portion of the ad begins to show the animated Flash video. Publishers need to enable pictorial ads in their dashboard in order to display the ads.
