Through the past 10 years in China, the following key developments in internet censorship and social media use have occurred: 1) In the early 2000s, the government began censoring the internet more heavily, blocking sites like Facebook, Twitter, and Wikipedia. 2) Chinese social media and blogging platforms emerged as alternatives to international sites, like Sina Weibo and Blogspot blogs. These saw rapid growth in users through the mid-2000s. 3) The government developed more sophisticated censorship techniques, like the "Great Firewall", to control the flow of information online and isolate dissenting voices, though some information still spreads.
