On 3 April 1973, the director of Research Development at Motorola, Martin Cooper, made the first phone call in history with a mobile phone.
But thas was just an experiment because only 10 years after the phone call of Cooper, the Motorola decided to produce a mobile phone with the cost of 4000 dollars!
As often happens in the world of technology, the invention of the mobile phone has evolved quickly moving from the analog to the digital (GSM, GPRS, UMTS / EDGE and so on) and still evolting today.
Over time, the mobile phone has changed assuming a key role in the society by carrying out many functions in addition to the 'simple' phone call that the first analog cellular (such as the Motorola 8900X-2, pictured) offered.
