Scott, your product is complete bulls***, plain and simple. I paid for my computer, I pay monthly broadband services, and you throw stuff up on there that I didn't want and don't need. Your popup banners come up when I'm creating documents for work, unbidden, they slow services and they act like a virus.
Don't try to pretend they're like TV advertising, because when I'm watching programming that I choose, unrelated ads don't fill up my screen or otherwise impede performance of the TV set.
What's more, when a popup launches, it makes that the active window (so if you are typing an email or webpost you will suddenly find yourself staring at a new "top level" window). Consider it akin to driving your car with the radio on, eyes on the road and suddenly your hands are not on the steering wheel and you are staring at the radio to hear the advertisement (it grabs your attention without your consent). Maybe you can turn the radio dial, maybe you are locked out of that choice. Your hands and eyes are permitted to return to driving but your activity has been disrupted by the "popup" radio ad.
There are some people who believe that when digital television is the norm, there will be digital blocks to prevent you from changing the channel during an ad (just like some DVDs don't permit you to scan/skip copyright notices, corporate logos, and ads/trailers).
