Social media has made censorship ever more challenging as web savvy users find ways around restrictions placed by governments.

From the Arab Spring, to Wikileaks, to Chinese micro-blogs the Internet has created an era where it is ever more difficult for states to keep their people ignorant and silent.

It has demonstrated that even oceans of difference aren't enough to keep us as a social species from socialising in online space, and that we can join our voices as a world in our calls for justice.

How would things have been different if social media was in South Africa in 1964?

Prezence Digital decided to create a video to try and answer that question as their 67 minutes for Madiba, though it took them a lot longer than 67 minutes to do.

The video is being launched to mark Mandela's 94th birthday, and is going to be featured on The Nelson Mandela Foundation for Memory website, as well as the foundation's YouTube channel.
