Once little more than a pornography filter, China\u2019s \u2018Great Firewall\u2019 has evolved into the most sophisticated system of online censorship in the world. As the Chinese internet grows and online businesses thrive, speech is controlled, dissent quashed, and attempts to organise outside the official Communist Party are quickly stamped out. But the effects of the Great Firewall are not confined to China itself. In this week's episode James Griffiths tells Carl Miller about his years of investigation into the Great Firewall and the politicians, tech leaders, dissidents and hackers whose lives revolve around it.
