If you happen to be in Turkey and are interested in soccer, I recommend that you tune in to DigiTurk, the channel that broadcasts soccer games nationally every week. During the games of the “Big 3” (the major teams representing Istanbul: Besiktas, Galatasaray, and Fenerbache), pay particular attention to the 34th minute  of the game. There will not be any sound. You will think that a technical failure has occurred or that the fervent fans have decided to stop chanting all of a sudden. You are wrong, because fans critical of the government’s  attempts to transform Gezi Parki into something else (a military barracks and a shopping mall) are chanting anti-government slogans and DigiTurk has silenced the service for which you have paid.
