Social Media: A History - Infographic

I've been a fan of social media for a while now and have used it personally for years. My new job, however, has me using it in the professional setting too. So, I've been talking to friends who work with social media and reading tons of articles, blogs, etc. to make sure that I stay on top of things.

I stumbled across this infographic today and thought it was interesting. Can you pin where you entered the fray?
