Ever since I started teaching comedy to teens, I have been a huge advocate of youtube channels. Want a career, start creating now. You create work showcasing your talents and you begin to market yourself to the world.
You don't really need a good camera. And you don't really need talent. Now making stupid 6-second videos can land you a TV or Film deal. Get a biog enough following on twitter, Vine, Youtube etc and you can sell tickets to your own shows, tshirts, ad space on your channels...
To many this idea seams bizarre and far fetched. For most it will be. But even those not getting famous over night, these tools develop talent and brand.
