Will AJAX Scrub IAB Impression Guidelines?

"AJAX is all the rage. It shows how to load "standard" Web content in completely different ways. But Flash has been able to do this for years. And there are many new emerging technologies, such as the Windows Presentation Foundation, that will make this type of dynamic content loading ubiquitous. Beyond the Web, there are the applications. Ad-funded applications are a huge focus for the software industry. Again, the Web 1.0 concept of refreshing the whole "page" of content breaks down in this model. In the scenarios listed above, current impression guidelines simply don't provide any significant guidance. The principles and thinking that went into those guidelines remain sound, but we must urgently address issues such as refreshing ads. Fortunately, the Interactive Advertising Bureau (IAB) and Media Rating Council (MRC) have started working on the problem. With luck and persistence, we'll craft new guidelines in time to resolve concerns -- and before we're right back where we started." Source: clickz.com
