In recent years many areas of our lives have been transformed by a move away from traditional technologies towards digital technologies. A few years ago people used traditional wired phones to speak to others for social or business reasons. These phones were in fixed locations, it never occurred to anyone to make a phone call while walking down the street or travelling in a bus or train.
Then digital mobile phones appeared on the market. They could be used almost anywhere and in addition to allowing voice conversations to take place, they could store contact lists and send text messages. Later models added the facility to access the Internet and take photographs or record video clips.
