Controlled and connected: 50 years of the cell phone - a podcast by BBC World Service

Fifty years on from the first mobile phone call, this programme examines how the device has revolutionised the way we lives our lives. It was 1973 when Martin Cooper, a Motorola researcher made the first mobile phone call to his rival at Bell Labs. The prototype weighed 2 kilograms and measured 23 by 13 by 4.5 centimetres. It offered a talk time of just 30 mins and took 10 hours to recharge. Fast forward five decades and checking the phone is the first thing many people do when they wake up in the morning and the last thing they do when they go to bed. How has the mobile phone revolutionised the way we live our lives?
