With a few clicks I am able to block all ads from being displayed on my screen. Companies that derive their revenue from ads and ad-serving come up with tricks to circumvent the ad-blockers, but at best these only work for the few days it takes an ad-blocker to get updated. If ad-blockers become mainstream, as has happened with pop-up-blockers, how will ad and content companies respond. One novel way would be to deliver their content through Flash, where the content and ads are interspersed in a way that cannot be blocked. This would put the content and ad companies back in control of their content. While this may turn off some readers, the majority would most likely accept it.
I wonder if the future of content is not RSS, but Flash.
