> I'm pretty sure that, the more we learn about how well advertising works, the less money people will be willing to pay for it. What's happening to billboards and newspapers right now is probably coming to several other industries soon. I don't see any evidence to support that. Total spending on advertising is increasing every year. Newspaper spending is down, Google & Facebook is way up. Overall it's up.
