When it comes to video advertising, there is perhaps no agency more heralded than the Harmon Brothers. They're behind some of the most viral video ads of all time: Squatty Potty, Purple, PooPourri, FiberFix, and the list goes on. They are famous for not just making humorous videos that go viral, but videos engineered to take people from awareness to buyers in just the few minutes the video is playing.
