Advertising seems to "work"...
As much as it is annoying to us all, and we all strive to ignore it, it DOES seem to work. This is because we are all talking about it.
Ad blockers are interesting devices. They are but one item in the never increasing battle between the eyes that look and the people who show. I suspect that eventually the result will be a draw, the declared "winner" keeps going back and forth. With ad blockers, comes web sites that detect them and don't display content, and so it goes.
As for TV ads, the wife desperately does all she can to skip over them (via TiVo), or mute them otherwise. I on the other hand seem to ignore them altogether, and assume that it is a perfect time for a potty break as necessary.
In the end, life goes on. If there were no ads, we would have two results:
1) Everything formerly supported by advertising would be more expensive (Newspapers, US TV, magazines, web content...)
2) Nobody would buy "new" things since they wouldn't know about them, which would drive up the costs there (supply/demand).
So, we're stuck with the current imperfect arrangement much as we ALL loathe it.
Life goes on.....
