I saw a program with the gentleman that does the voice of Sesame's Street's ELMO. It was pretty amazing, I never realized how much money you can make just by providing your voice. He makes hundreds of thousands of dollars a year. Just think of the other famous characters that provide voices for cartoons like the Simpsons and the powerful voice in movie trailers. The movie trailer voice makes millions, it sounds like the same guy is doing all of them. Singers are another group that makes a lot of money using their talented voice.
