I think most people are unaware how much in advertising is about manipulating feelings. I ran across this entry on a real estate blog and found this little example both funny and insightful:
If you never noticed all the bare feet in new home ads, you will now (sorry). Some marketing consultant long ago noticed that bare feet suggests the comforts and coziness of home. Doesn't the couple in the picture look like they have the life all of us want?
Bingo. And now you will notice it consciously, where before you noticed it only at gut level.
