Why did the government of Iran have difficulty preventing information from getting out of the country during the 2009 election protests

The authoritarian regime of the Iranian clergy censors the press and has close control of the flows of information. Even though, news about protests in 2009 spread through social media and the use of cell phones. Even in such undemocratic regimes, it is very difficult to have absolute control because of the internet and new technologies.

A.) Ordinary citizens used thousands of different Internet file sharing sites and e-mail accounts, as well as Twitter, to transmit information.

Explanation:

The Iran government didn't have control over social media sites on the internet such as Twitter and therefore, could not stop the spread of information to the United States.
