Once the Egyptian government cut the Internet, the protests in Tahrir Square were joined by protests across the country.
What’s the News: Social networking has been a star of the Arab Spring revolutions. People can’t stop talking about how Twitter and Facebook helped protestors organize, and when Egyptian president Hosni Mubarak suddenly cut access to the Internet and cell phone service on January 28th, many wondered how the protestors would share information and keep momentum. But as it turned out, depriving people of information had an explosive effect—far from the epicenter at Tahrir Square in Cairo, so many grassroots protests sprung up that the military was brought in. Two weeks later, Mubarak resigned.
