Graphic: Rise of the mobile phone
Forty years ago this week, reporters watched amazed as Motorola electrical engineer Martin Cooper made the first public mobile phone call — to his competitor at Bell Labs, no less, reports Kristopher Morrison. It took 10 years before Motorola went from demo in New York to producing the first model for retail. Since then the technology has surged and this week Mr. Cooper said he believes the best is yet to come. “Technology has to be invisible. Transparent. Just simple. A modern cellphone in general has an instruction book that’s bigger and heavier than the cellphone. That’s not right,” Mr. Cooper told CBS.
