On April 3rd 1973, Martin Cooper made the first mobile call on the nine-inch (and 28-ounce) Motorola DynaTAC. Dialing up a rival at AT&T, he apparently said that he was ringing "to see if my call sounds good at your end." While briefcase-size models had come before it, it's Motorola's truly mobile phone that became the go-to power accessory for the likes of Gordon Gekko, Zack Morris and, er, American Psycho's Patrick Bateman. Since its heyday, however, the AMPS analog networks that the phone used to run on have now largely disappeared, replaced by digital ones that have added better call clarity, not to mention data connectivity at ever-improvingspeeds. We've come a long way.
