Well actually, many people who are in full control of their minds already pay for you to see their ads. I shall call them Big Business. In fact, advertising online has become a BIG business. I will pay you X dollars to show my ad to X number of people. If I make a clever ad, and they buy, I, Big Business, will pay you more money to show my ad to more people.
Advertisers go to where big groups of people are.
They pay money to the middleman who can gather big groups of people. These programs cut out the middleman. The internet allows the advertiser to show ads to millions of people, one ad at a time. THAT is what is important. So, for example, if you are a college student, you will be able to see advertising about entertainment, sports, cars, and employment.
