This is in addition to those TSA "shoe bins" that now have advertising on them and drop-down tray tables on certain airlines that also have advertising stickers on them.
Since "cutting edge" gas pumps now blare commercials to us as we're pumping our gasoline, we can also be treated to flat screen TVs blaring commercials to us as we're dining at places like Denny's. I've heard that some cash-strapped cities like Colorado Springs are considering advertising emblazoned on the sides of their school buses and police cars.
In the movie "Idiocracy", which takes place in the future, Luke Wilson's character has to confront a judge in a courtroom scene. There is advertising emblazoned all over the judge's bench and on all the walls of the courtroom.
Give it time, my friends. We'll probably see that in our lifetimes.
