Mobile phone technology has come a long way since the first mobile phone call was made 40 years ago today, changing life forever- but there is a lot more innovation to look forward to, according to one expert.
It was back on April 3 1973 that Motorola employee Martin Cooper made a call in New York on a Motorola DynaTAC - widely regarded globally as the first public cellphone call.
Something of a brick - you would be probably better off mugging someone with it than for it - the first mobile phone was used by Cooper to phone a rival at AT&T's Bell Labs on 3 April 1973.
We can imagine the response that got, but expect that the call was rather short anyway, particularly as the phone had terrible battery life, weighed 2lb and Cooper was probably sick of holding it up to his head. Mobile phones hit the UK in the mid 1980s, but were expensive and still rather large.
