I think the whole advertising situation will get better once the tech bubble bursts.
You seem curiously convinced that A) we are in a bubble and B) that advertising will go away or "get better". You can't really know A for certain by definition because bubbles generally can only be identified in retrospect and B will never ever happen. It's unclear what "get better" means to you but I'm pretty sure whatever it is won't happen.
My prediction is that eventually the industry will fall apart as companies realise the ponzi nature of current advertising prices, and that much of this expenditure is not converting in to sales.
I think you don't understand the advertising business. You think that companies are naively throwing money at advertising because they don't know any better. While there are some out there where that is true for the most part buyers of advertising understand very well the relationship between advertising dollars spent and the returns they get. It's not at all hard to get a pretty solid idea of the correlation between ad spend and revenue.
