Yeh Kaz, ads r the easiest (in my opinion) type of material 2 relate consumerism with bcos there is just so many product-based ads out there these days.
Try nd go 4 big name American companies such as Macca's and Coca-cola.........
Nd also make sure the ads u choose relate in some way or another 2 the consumer relying on the product......for happines or wealth etc
There's plenty out there
