Contributor(s): Professor Nick Couldry, Dr Ellen Helsper, Professor Sonia Livingstone, Svenja Ottovordemgentschenfelde | Welcome to LSE IQ, a new monthly podcast from the London School of Economics and Political Science. This is the podcast where we ask some of the leading social scientists - and other experts - to answer intelligent questions about economics, politics or society. In this episode, Jo Bale investigates social media amid growing concerns that tech companies are putting profit before the well-being of individual users and democratic societies. She talks to Nick Couldry, Ellen Helsper, Sonia Livingstone and Svenja Ottovordemgentschenfelde of LSE's Department of Media and Communications.
