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. Is the Cambridge Analytica scandal just the tip of the iceberg? It has revolutionised the way we communicate, but some are saying social media has now become a social problem. 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.
