In a commercial that you may have seen, where did merchandise such as towels, shirts, and handbags, as well as happy shoppers and figures like "50% off" and "$9.99," appear?

Inside colored squares moving across a black background
On the turning and flipping pages of a wall calendar
Projected onto high-tech screens and billboards in a city
In pale blue comic strip-like bubbles over people's heads
