I've been hearing more and more stories of people, who are now famous, getting discovered through YouTube. Latest being the young lady in the Diet Dr. Pepper commercials. Do you post to these sites in hopes of being the next big thing?
Yes, I think YouTube is one tool that can be used to help people become famous. The question is whether people are successful because of YouTube, or just that people who are successful happen to have used YouTube but would have been famous eventually either way. It usually takes talent to maintain
fame and not just be a flash in the pan. There are also different levels of fame. Michelle Phan, the girl you mention, just booked one commercial and is hardly a household name yet.
Do I use YouTube, and other social media, in hopes of furthering my career? You bet. For anyone remotely related to the entertainment or media industry - like actors, singers, writers - you'd be a fool not to. (Now, if you're a grade school teacher or research scientist, that's a different story.)
