If the circus is coming to town and you paint a sign that says "Circus Coming To Town", that’s advertising.
If you hang the sign on an elephant and parade the elephant through town, that’s promotion.
If the elephant walks through the mayor’s flowerbed and destroys it, that’s publicity.
If you can get the mayor to laugh about this, that’s public relations.
If you stand outside the tent with a megaphone and tell the townspeople what a great time they will have at the circus, causing them to enter the tent and spend lots of money, that’s sales.
And if you planned the whole thing IN ADVANCE, that’s marketing!
Does your business have a marketing plan?
