The first mobile phone service, for 80-pound telephones installed in cars, was demonstrated on June 17, 1946, 75 years ago. The service was only available in major cities and highway corridors and was aimed at companies rather than individuals.
The equipment filled much of a car’s trunk, and subscribers made calls by picking up the handset and speaking to a switchboard operator. By 1948, the service had 5,000 customers.
The first handheld mobile phone was demonstrated in 1973, nearly three decades after the introduction of the first mobile phone service. It was nearly three decades after that before half the U.S. population had a mobile phone.
