Their advertising of Oakley and other products definitely let's you know who pays the bills. Every other seen Ron changes lenses, Bobby wears different pairs as well as numerous characters on the show. Bobby even left the hospital in an O t-shirt. Ron was wearing a polished white half jacket with jade iridium then they turned to ice lenses outside a debate and once inside they magically turned backed to jade. I would think the commercials where enough to pay the bills as production of "reality tv" is much cheaper then say an episode of Friends. You constantly see logos being blurred out. I think they purposely load the scenes with as much advertising as possible then blur anyone not willing to pony up funds to keep them in the scenes.
