There were no cell phones
Remote communication in 1968 was limited to the postal service, landline, or pay phone. It wouldn’t be until the early 1970s when Motorola and Bell Labs would become locked in a race to bring the first portable phone to the market. In 1973 Motorola placed the first call on a prototype for what would in 1983 become the world’s first cell phone. Today, cell phones have all but replaced tethered lines.
