Ever since Bell patented the telephone in 1876,we've been living in the age of instant communication. But there has always been a restriction-you need to find a phone. And that isn't always easy. Ok,we've had car phones since the 1950s. But the first car phones were enormous. The machinery filled the boot of the car! More than a portable phone, it was a mobile phone box! One of the first users was a doctor in Sweden. Unfortunately,the phone needed so much power that he could only make two calls before the battery went dead. The first to his patient,and the second to the garage to get someone to come and fix his flat battery. By the mid-1960s phones were small enough to fit into the front of a car,but unfortunately,they were still too heavy for people to carry around. They were also extremely expensive.So,it was no surprise that they didn't become popular
