Money advertising placements is an idea conceptualized by Michael Marcovici.
Michael Marcovici thinks money is a very fluid media placement because "it changes hands on average 3x per week, so each ad on a 100 USD note is seen by more then 1000 persons." To visualize the concept, Michael Marcovici has made some of his own money prints with Mattel, American Express and Campbell's replacing the presidents on the bills.
Implications - Michael Marcovici's idea to place ads on paper money is truly innovative and displays some out-of-the-box thinking. Next time you get some change back from a cashier, be sure to check out both sides of your paper money.
