I don't run Adblock the software, but I seldom see ads. I am so tuned to ignoring them that my brain just blanks them out. About the only time I am aware of them is when they are truly obnoxious with blinking or flashing.
I sometimes wonder what would happen if ads were cut back to 1/100 or 1/1000 of the current frequency, if ads were such novel events that I did pay attention to them. From an admaker's point of view, you can't cut them them back so far as to become affordable only to huge corporations. But if I only had a few hundred in view in a single day, counting computers, magazines, billboards, ads on taxis and buses and so on, and there was little repetition, I might just actually be aware of some of them.
