The first 'cell phone' had a noble cause. It would allow people to move about and still make important phone calls from one phone number.

Dr Martin Cooper, a former general manager for the systems division at Motorola, is considered the inventor of the first portable handset and the first person to make a call on a portable cell phone in April 1973. The first call he made was to his rival, Joel Engel, Bell Labs head of research.

The Cell Phone was about efficiency and making it easier to carry on a business conversation.

It converged technologies to make it happen.  A wireless device that would use airwaves rather than wires to transmit voice signals.

Then.

Something went ? wrong ?

Someone got greedy and marketed this seemingly safe entity of society as a consumer product.  A consumer product that was supposed to be benign, all of a sudden wasn't.
