Let's see how people in Iran are using media to make their voices heard when all media outlets have been subjected to government pressure and censorship. After the suppositious election  in Iran, most of the internet had been filtered and there were no any other media, such as radio or television, where people can exercise their freedom of expression. Moreover, all the opposition newspapers had been banned.
However, Iranian people have used their cell phones and computers to disseminate information about the green movement and it was remarkable as they succeeded in communicating with the outside world.
Now, they have found another way to make their voice heard. They gather in any places where governmental media are placed, such as football stadiums.
For instance, few days ago there was a football match in Iran and people gathered in the stadium and started protesting the government and shouting slogans against the dictatorship and it became a scandal when the government censored the shouting when it was relayed on the Iranian television.
They were also gathered for another match between two famous soccer clubs in Tehran and this time you would be able to hear their voices when they are shouting slogans. They were saying:”We don't like political football matches.” As recently, the Islamic Revolutionary Guard Corps  spent huge amount of money on football to make a black market and get the benefit of that.
In another case, people call in during live shows that stream on government’s television and talk about the green movement in Iran.
Here you would be able to see how people are making use of social media:
People in stadium are looking for their votes.
People are against political sport.
