You guys seem a bit confused so I thought I'd give my 2 cents.
If your sponsored by a company, trucks wheels, shoes, boards anything really, your part of their skate team. You usually don't see companies like Spitfire or Royal releasing skate vids I know but you might get the occasional one free in a magazine or something. Shoes and Boards make vids with their team (obviously).
Oh and you can be sponsored by more than one company as long as your not sponsored by two board companies. Only works with Boards, Shoes, Trucks, Wheels Clothing etc. Only allowed one of each though. But if your sponsor finds out your riding a board other than theirs they ain't going to be happy...
P.S: Adio shoes suck.
