Ads are designed to be seen. And we do see them.
I drove from West to East one time and while going on the 10 in Texas, after several hours I noticed that each few minutes or so, my thought process was being interrupted by a billboard explaining me what I could buy at the next exit. McDonalds, gas, Tourist info, Indian reservation etc. etc. Me myself and I, on the Highway to the East, and still, not the space to some thinking on me own. I took the next exit and started taking smaller roads (that were still big enough Texas, you know) off the main road and really, the difference was tremendous. Not a single billboard and there was so much more space for 'me' instead of particles of me-being interrupted by messaging of parties wanting to make money on me…
I have numerous other instances where I was conscious of the continuos messaging around us, trying (with success) to steer our beliefs system towards certain styles, products and brands but this was one of the nicer ones.
A fresh example is the movie trailers on youtube. Have you noticed some smart moneymakers place free trailers (commercials in itself if you think of it) with an ad of 15 seconds in front of it?
All outwash of the Capitalistic system. I wrote about it before. We don't want them, but for some money, entertainment, some easy quick fix, we'll allow them to get in our face more and more. I try to steer away from them as much as I can. Like ditching the telly and download the stuff I really want to see.
Time to awaken.
