"If the circus is coming to town and you paint a sign that says "Circus Coming to the Fairgrounds Saturday", that's advertising.
If you put the sign on the back of an elephant and walk it into town, that's promotion.
If the elephant walks through the mayor's flower bed, that's publicity.
And if you get the mayor to laugh about it, that's public relations.
If the town's citizens go to the circus, you show them the many entertainment options, explain how much fun they'll have spending money at the booths, answer their questions and ultimately, they spend a lot at the circus, well that's sales.
And if you planned the whole thing, that's Marketing!"
