Marketing Defined

“If the circus is coming to town and you paint a sign saying, ‘Circus is coming to Fairgrounds Sunday’, that's ADVERTISING.

If you put the sign on the back of an elephant and walk him through the town, that’s PROMOTION. 

If the elephant walks through the Mayor’s flower bed, that’s PUBLICITY.

If you can get the Mayor to laugh about it, that’s PUBLIC RELATIONS.

And, if you planned the whole thing, that’s MARKETING!”

The quote is attributed to P.T. Barnum of Ringling Brothers and Barnum & Bailey Circus in 1871 on many online sites. However, I can't verify it with all certainty.
