None of this seemed to be aiming at getting anyone depressed. Every single one of those adverts gave the message "If you don't buy this product you'll be unhappy/unattractive/hungry/missing out/uncool." Every single one. None of them aim to make people depressed, but they all do exactly that if you don't buy the product. It's worth noting that all the adverts you remember are for products that were wildly successful at the time. People are very willing to pay to avoid being unhappy, even if when the message is coming from a cartoon rabbit.
