Need How to Articles for Facebook, Twitter & YouTube

I need some an article that basically explains what Facebook is (and what a Fanpage is), how it works and how one can use Facebook (and Fanpage) for their business. I plan to use this to make a power point presentation to talk about Facebook. I also need the same thing done for Twitter and Youtube as well. Screenshots showing how to setup accounts will be needed for all three as well so I'm able to show them how to setup these accounts. I don't want you copying someone else's stuff, so please try to be unique and not steal someone else's content. I need this back ASAP-- within 24-48 hours (must have back no later than Sunday).
