I've added a GoogleAds rectangle on the right side of the blog (plus another rectangle with the Google search). Be sure that I won't get rich; in fact, it does not generate a single penny, it seems.
Nevertheless, it's fun and you may try to click at some of these ads. Some links offer free copies of Anthony Zee's textbook on Quantum Field Theory. Other links promote a book that allows you to create reality using the holographic principle. Not surprisingly, the crackpot McCutcheon with his book The Final Theory is among the links being offered, much like John Hagelin.
More serious advertisements offer you particle counters, plasma physics magazines, courses on quantum theory, and many other things. The physics ads market is not terribly advanced so far, but some diversity is already out there. If you happen to see some very interesting ads, you may share your excitement. ;-)
The advertisements depend on the content, and therefore you're offered pollution-free solutions and news about global warming if you look at articles about the climate.
