1st mobile phone call was made by inventor to troll competitor
Motorola engineer Martin Cooper, who invented the handheld cellular mobile phone, made the first-ever mobile phone call to brag about his achievement and troll his competitor AT&T's Joel Engel on April 3, 1973. "Joel, this is Marty. I'm calling you from a cellphone, a real, handheld, portable cellphone," he had said as he walked on the streets of New York.
