12 of the Best Marketing and Advertising Campaigns of All Time

I’ve always been a little leery of proclaiming anything "the best." I never declared anyone my best friend as a kid because I was afraid my other friends might assume I thought less of them.

So it was a little difficult for me to come up with just one "best" marketing campaign of all time -- which is why there are 12 in this post instead.

Why are these 12 marketing campaigns some of the best of all time?
