The cellphone has come a long way since 1973, when Martin Cooper, an engineer at Motorola, called Joel Engel at AT&T to let Engel know he had lost the race for a new technology. Host Llewellyn King and Co-host Adam Clayton Powell III discuss the cellphone as an instrument of change with Christopher Guttman-McCabe, chief regulatory and communications officer at Anterix.
