You're probably affected more by them than you think. It all depends what you watch, because based on that, you're being targeted for specific items. For instance, I watch a ton of ESPN and sporting events. The vast majority of commercials I see are for beer, snacks, other kinds of food, and products that my demographic (upper teens to early 30's and even into later years) would have interest in (i.e. body sprays/deodorants, sports equipment, televisions/electronics, etc.) So, I'm a lot more likely to buy Budweiser or Miller, Doritos or Fritos, fast food if a burger looks good on TV, Axe body spray, etc just because that's what I see most, and that's what I see pictured as "quality," "normal," and, in many cases "sexy."
