Twenty years on from the invention of the world wide web, this major new series takes stock of its profound impact – how, for better and for worse, the digital revolution is reshaping our lives. Over four themed episodes that criss-cross the globe, journalist and academic Dr Aleks Krotoski explores the meaning of a phenomenon that is transforming everything, from how we learn to how we shop, vote and make friends. With a quarter of the planet connected so far, this series examines what is in store for the remaining 75 per cent of the world's population as they come online.
