That once seemed like a good idea to me, but several companies tried this during bubble 1.0 and they all flamed out spectacularly. The trouble, it seemed, is that it just isn't an effective investment of people's time. Anyone willing to get paid $X/hr to watch an ad doesn't have enough disposable income to make it worthwhile to spend $X/hr on their attention. The market doesn't clear and the price just shoots to zero.
