People don’t like to feel like they’ve been tricked. They don’t like to be drawn into a story and then learn that story is somehow a calculated concoction designed to get them to buy stuff. However, people also don’t like ads. They don’t trust most ads. They ignore them, change the channel, etc.
So should we get mad when an “ad” doesn’t say it’s an ad – doesn’t have a product name prominently displayed, but draws you in and makes you smile, get a little nervous butterfly stomach flutter and leaves you feeling warm and fuzzy because we didn’t know that we were being “sold.”
