In 1973, Motorola scientist and inventor Martin Cooper ushered in a new era of voice communication by demonstrating the first personal cellular phone handset, the DynaTAC.1 By 1983, the device was commercially available, cost almost $4000, weighed 1.75 lbs, and required a 10-hour charge to deliver 30 minutes of talk time. Although the principle of wireless communication would eventually revolutionize the way humans communicate, initial interest in mobile phones was so low that telecommunication companies had to create and market reasons for using them.2 In 1973, no one could have predicted how cellular phones would transform society or even how they would eventually be used.
