In the good 'ol days, marketing was easy. If I wanted to sell coats in 1905, all I would have had to do was put up a billboard that said "BUY BEN'S COATS!" and everyone would buy one until I had no more coats.
Okay, so maybe that's not true. Maybe it wasn't that easy. But compared to marketing in 2014, things were far simpler. The truth is, from the advent of advertising to today, we've evolved tremendously.
Marketing strategies have become far more complex and immense in scope - even in the past ten years! Why? Because they had to.
