It has revolutionised the way we communicate, but has social media become a social problem? It connects us with people all over the world and helps us stay in touch with friends and family, but it appears Facebook is also a vehicle to manipulate users. Many are now asking whether the Cambridge Analytica scandal is just the tip of the iceberg. At the Roundtable was Emily Taylor, CEO of the Oxford Information Labs; Managing Director of digital marketing agency Yellowball, and Mona Elswah from the Oxford Internet Institute. Roundtable is a discussion programme with an edge. Broadcast out of London and presented by David Foster, it's about bringing people to the table, listening to every opinion, and analysing every point of view. From fierce debate to reflective thinking, Roundtable discussions offer a different perspective on the issues that matter to you. Watch it every weekday at 15:30 GMT on TRT World.
