In 1945 William Durham started DURHAM RADIO SERVICE, an AM radio (television came later) retail business in the small farming town of Mesa, Arizona. Since that time the electronics industry has gone through many evolutions as has Mesa and Durham Communications Inc. One of those evolutions was the increasing demand for 2-way radio. To meet that demand, Durham Communications Inc. has grown into one of the largest locally owned Wireless Communications companies in Arizona.
