The first newspaper ad in America appeared back in 1704. Since then, the advertising industry has undergone a considerable transformation. Over the years, we have seen dozens of ads that have done much more than persuade us to buy a product or service. The very best campaigns have affected how we communicate and interact with one another, from the coffee breaks we enjoy to the clothes we wear to work to the videos we share online. It even comes down to details like diamond engagement rings, orange juice, and Santa Claus.
