Product placement (and advertising in general) annoys me so much that I'm actually less likely to buy their product later on. I can admire a well-constructed ad, but it almost never actually affects my purchasing.
There are a lot of famous commercials, which made a real impact with people, but the majority of people had no idea what they represented. LOL
Sorry to bring up a side thought, but...
I was delighted to see one of my favorite commercials is again being played on T.V. Not a remake or an update, the original commercial. It's a classic, and unlike some like the "Mean Joe Green" Coke commercial, it is not obviously dated. Some things just never change, I guess.
I am, of course, talking about the old (ancient?) commercial in the USA for "Discount Tire Company".
A calm, relaxed voice says in voiceover: "if you ever are unsatisfied with one of our tires, please feel free to bring it back".
The action you are viewing is an old lady. She has what looks like a permanant scowl on her face. She is rolling a tire up to the store.
She picks it up, swings it a bit to build up momentum, and then flings it through the glass window that says "Discount tire company".
The calm voiceover in the back says simply "Thank you.... Discount Tire Company".
A true classic.
