Everyone from stay-at-home moms to entrepreneurs to musicians to comedians are creating a new or second career and earning income by posting videos on YouTube. No longer do you need an agent or manager to launch a singing career or to publish a book. No longer do you need a company behind you to sell your ideas, products or how-to knowledge. Six years ago YouTube.com launched on the web and revolutionized video sharing. What began as a simple idea — allowing anyone to upload and view videos, for free — quickly transformed into a platform that connected the world. Now, YouTube encompasses everything from how-to videos, to entertainment to self expression to business to citizen journalism. “20/20? reports on the phenomenon and talks to many whose lives have changed personally and financially from their YouTube success, including singer Greyson Chance, two of YouTube’s biggest stars – Mystery Guitar Man and beauty guru Michelle Phan – and the comedic brains behind “Key of Awesome” one of the largest spoof channels on YouTube.  Generation YouTube airs on  “20/20,” FRIDAY, SEPTEMBER 23 (10:00-11:00 p.m., ET) on the ABC Television Network. Deborah Roberts, Juju Chang, John Berman and Ashleigh Banfield report.

“20/20? is anchored by Elizabeth Vargas and Chris Cuomo. David Sloan is executive producer.
