Technology has indeed come a long long way in the last century. way back in 1959 the UK introduced the very first pay phone system whereby the general public could make a telephone call from a public call box. These new coin phone boxes have slots for 3d, 6d and 1s pieces.
The system was launched by the Queen who made the very first call which lasted 2 minutes and 5 seconds to Edinburgh. The call cost four pence.
Of course these days we have mobile phones, VoIP, Skype, instant messaging, texts online chat etc. How times have changed.
