The Arab Spring technically began in 2010, but didn't gain traction and international awareness until early 2011. Protesters in countries including, Tunisia, Egypt, Syria, Yemen, Libya and Bahrain took to the streets demanding change.
But the revolution wasn't televised, rather it was tweeted, Facebooked and YouTubed. The protesters used social media to organize, mobilize and document the events with such success that Egypt shut down the Internet and cell phone networks on Jan. 27.
