We all know that most of the Internet is funded on ads. And I personally think this is OK: creating content and managing all the details of a site takes time and sometimes cash. Like radio or TV shows, creators of content need to find funding through ads. This is even more important for a solid industry in Internet. Just imagine this: there would be no social networks, Google, or any other free service if there weren't ads. But some people don't like ads. I'm not one of them, but some find ads so annoying that they would pay to get rid of them. This is already true for some mobile apps, mostly for Android. But what if you were willing to pay to get rid of ads in a regular website? Apparently, this is the question that they asked in Google, and the answer is Google Contributor, an experiment to eliminate ads in the sites you visit.
The idea is simple: you choose a contribution to be paid monthly to the participating sites and you'll see no ads there. Instead, there will be a "Thank you" message where the ads were before.
Ok, I don't see any ads and the content creator just said "Thank you". Is that all? Am I paying just for that? In short, no. The most important benefit for the user is something that everybody is losing online: privacy. Without ads, no one needs to track your preferences or your activity just to show you the right commercial offers. I'm pretty sure there are some people that totally would pay for that. Also, there's some controversy about advertisement as a source of revenue. For example, take into account this SWOT analysis for Facebook. Advertising as a source of revenue is taken as a weakness.
For now, Contributor is only an experiment, and you need to join a wait list to get and invitation and try it. However, this could be a new market for funding the web that's unexplored yet.
