1) The industry is finally realizing that a massive amount of people got pissed by flashing display ads. Up to 14% of the online population uses an ad blocker (much more on HN :).
Last month, the IAB published their new guidelines, including max CPU usage for Flash banners: http://www.iab.net/iab_products_and_industry_services/508676...
I'm working on a product that helps publishers verify that CPU usage from ads served on their site does not exceed their specs, http://www.clarityad.com
Adobe is also investing in this, with their project Adthenticate http://labs.adobe.com/technologies/adthenticate/
