At the South by Southwest interactive conference in Austin, Texas, we find out how new media is being used to drive social change. We hear about the role that protest plays in creating communities. We meet a Harvard student pressurising her university to give up its fossil fuel investments. And, Vivian Graubard, technology adviser to the White House, speaks about her passion for the issue of immigration. A young blogger in the US pushes for change in Egypt. And an investor in start-up businesses hopes to harness the creativity of entrepreneurs to counter the social media strategy of Islamic extremists.
