Search and Advertising: The Invisible Hand

I will be speaking at the FT Digital Media and Broadcasting Conference on March 9-10. 

The topic I've been given is Search and Advertising: The Invisible Hand. 

"Web 2.0 has dramatically changed the way users' interact with online brands. Search engines have become the main portals through which users select and access products. But to what extent can search precisely target demographic as well as geographic groups and give the user the content they want and the advertiser the exact profiling they require? As search engines and software applications become cleverer, could advertising seem so relevant that it will no longer seem like advertising?"

So what do you think? 

The lines between content and advertising are blurring. I'd love to hear your thoughts. Post a comment or send me a mail.
