Russia has now over 102 years of experience
By giving such an exact figure it's clear that you're thinking about the Russian Revolution as being some sort of turning point, but it wasn't. You can go back much further than the rise of Communism. The tsars also imposed political censorship, from at least Peter the Great's time, while in the centuries before that censorship was primarily a tool of religious orthodoxy.
The same can be said for China under the warlords and the emperors. Censorship has been going on far, far longer than the days since the Long March.
