In the UK, Dixons have bought a company which sells mobile phones. The company is called Carphone Warehouse. If you’re younger than 40, you might be aware that mobile phones once looked like this: That’s the Motorola DynaTAC, with engineer Martin Cooper who made the first mobile phone call. The DynaTAC went on sale in 1984. Before that, there were even larger semi-mobile phones called carphones. They consisted of three parts: a handset, which generally looked like the DynaTAC; a control panel which was mounted into the car dashboard; and a box the size of a small suitcase which often went in the trunk of the car and contained the actual phone circuitry.
