I like to think about advertising as a complete mind f*ck. I love it because you can manipulate the way someone views an image or video by tweaking virtually anything in the image. 

for example: 

Without the words in the picture, its just john goodman in The Big Lebowski. Though this isn't really an advertisement its just a meme but the concept behind it is relatively the same. Not only do ads persuade, but they also create images and brands which can often be synonymous with your personality. It's a double edged sword when an ad can tell you if what your drinking is considered cool or what breath mint you choose will let you get laid. I feel like it creates less individuality within people because ads can sway someone's opinion on something so much its as if your not thinking for yourself.

I also just like the art of an ad. all the ingenuity an ad must be is pretty awesome.
