The Interactive Advertising Bureau (IAB) issued guidelines (nearly identical to those published in May soliciting feedback) for "broadband video commercials" - ads before, during or after broadband content, including video and games, writes ClickZ. IAB said the guidelines "were developed to further enhance the user experience without constraining creative opportunities for marketers and will improve the efficiency and ease of planning, buying and creating online media."

The guidelines suggest ad lengths be "up to :30" for those before or during content, but no recommended length is made for post-roll ads. Fast-forwarding should be disabled during ad play, the IAB suggests.

Advertisers should present ads in a 4:3 or 16:9 aspect ratio, at a minimum encoded bit rate of 200 Kbps, wit the minimum suggested panel size at 300 x 225 pixels.

The guidelines are also available in PDF format.
