New IAB Revised Ad Unit & Rich Media Creative Guidelines

The Interactive Advertising Bureau (IAB) has put out its "Revised Ad Unit
and Rich Media Creative Guidelines."

The guidelines:

* Address minimum guidelines for common ad formats and sizes such
as banners and buttons as well as transitional and various over-the-page
units such as floating ads, page take-overs and tear-backs;
* Define rich media as separate from basic animated ads by
requiring interaction aside from the ability to click-through;
* Cover ads delivered into standard web environments including
email and static and dynamic web pages; and
* Update the minimum file sizes of the 2002 Universal Ad Package
