Commercials are generally used to advertise something to invite you in and make your interest spark. Anybody ever heard of a Fuji ball? The commercial is actually pretty cool it looks like this could be done and done easily they give you a small example of what can be done with it. The guy who demonstrates there Fuji ball is excellent with it and I don't know if you have ever used one of them before but its literally a ball that has a clear surface, with a reflection in it and the operation of the ball is surprisingly challenging, but that's the point. There commercial sparked the interest of a lot of people and they made a good grip of money off of this ball that's essentially worthless in my opinion because it's so difficult to use. Commercials are in all essence a way of distributing ideas and products through things that people use and are forced to sit through but if 1 of 1000 of a billion people buy's your stuff then your doing it right!
