Air date: Apr 20, 2017
Timeshift tells the story of how Britain's phone network was built. Incredibly, there was once a time when phones weren't pocket-sized wireless devices, but bulky objects wired into our homes and workplaces. Over the course of 100 years, engineers rolled out a communications network that joined up Britain - a web of more than 70 million miles of wire.
