Tech Life

BBC World Service

Tech Life discovers and explains the ways technology is changing our lives, wherever we are in the world. We meet the people with bright ideas for rethinking the way we work, learn and play, and get hands-on with the products they dream up. We hold tech giants to account for their huge power to affect our lives, and ask who wins, and who loses, in the technology transformation. Tech Life is your guide to a future being made, and remade, at lightning speed in front of our eyes.
