The local airport has "free" WiFi ... free, that is, if you agree to watch a sponsor's ad. You get a list of sponsors, and you can choose whose ad to watch.
We all know Google's billions are primarily advertising revenue. Is this the model of the future? Maybe we can eliminate lots of payments simply by agreeing to watch ads. Those folks in Tennessee whose house burned down because they failed to pay the annual fire department fee? Suppose they could simply have agreed to watch a Geico ad in exchange for fire fighting service? Okay, that's a bit cruel, but some insurance ad. As long as it wasn't an infomercial, some of their property and pets might have been saved.
Could this model be extended to cover police, sanitation and other services?
Isn't this really the best answer for health care? The more serious your condition, the longer you're likely to be laid up. And while you're taking up a hospital bed, you can be watching all the latest Nasonex or Cialis ads. (Of course, sponsors might not want to cover terminal patients.)
Ultimately, if you can pay for everything by watching ads, then even the goods and services that are advertised will be paid for by watching other ads. Hmmm. This has possibilities.
