Google already offers something like this with Google Contributor. You load a fixed amount onto your ad-free pass, select which publishers you want to browse ad-free who have opted-in, and it will deduct a small amount (typically 1 - 4c) for each webpage you view ad-free.
The catch is, publishers don't seem to be signing up, presumably because they're making far more than 4c / pageview by showing ads to you. The publishers I added seem to have all abandoned the program long ago. I've been a member for over a year and have still only spent 6c.
We really need some form of frictionless micropayment system that goes directly to the publishers.
I would gladly pay for ad-free web content (for example, NYT and WSJ) if they made it possible for me to pay them via a consumption based model instead of trying to force me into an expensive yearly subscription.
Right now publishers make zero from me because I have a couple layers of ad blockers. If I'm willing to pay X for some number of ad-free articles, which does not have to be unlimited, then publishers would be making X dollars more.
Yup. That's why I don't pay for HBO, so I totally get it. If they want to make it $2, at least they'd get something from me. Until then, there's always Putlocker. Their loss, really.
