all major sites (amazon, yahoo, gm, chevrolet, NFL, NBA, MTV, etc, etc) use flash based ads. Some ads require the use of Flash Player 7 which is in most modern browsers already. If yours does not have it then it prompts you to upgrade or install. No big deal. A simple upgrade will avoid any prompts for the player. We are not going to refuse flash ads from any advertiser due to the fact that it is an accepted standard on every major website on the internet now.
