  • Resumen

  • The cell phone was celebrating its 50th anniversary last month. On April 3, 1973, Martin Cooper, an engineer at Motorola, made the first public call from a mobile phone. This first model, called the DynaTAC, was a large device the size of a brick, weighing 2.5 pounds, and costing nearly $4,000. - Bruno Guglielminetti
