Indymedia was a global network of Independent Media Centres (IMC) which saw its heyday in the first two decades of the 21st Century. Self-organised networks of local activists covered international resistance to capitalism, ecocide, neocolonialism and many other local and international struggles. Indymedia became synonymous with the issues taken up by the Global Justice Movement. Powered by the internet and built on IMC servers, Indymedia embodied the ethos of DIY journalism and autonomous media. It is a vital part of the pre-history of social media and digitally-enabled activism.
