It makes me wonder where all the public outcry was when magazines, newspapers and book publishers began charging for their wares. What is so different about digital content? The web is not radio or TV. How a market with infinite competition can be uncritically compared to protected markets, like radio and TV, is beyond my comprehension.
This "business" model also assumes that surfers would only have one browser open at a time. While an ad is displayed in one window, surfers could be interacting with another. In the AllAdvantage model, hackers always always several steps ahead of the accounting system, which hastened the company's demise.
This also sounds a lot like time-share vacation marketing: "If you view our ad, will give you a free breakfast and TV". Inane ad programs would also reflect poorly on the company's brand and content.
