Martin Cooper, who made the first cell phone call in 1973, holds a Motorola DynaTAC, the first prototype of a cell phone. The first commercial call wasn’t made until 10 years later.

Our reliance on cellphones began 35 years ago today
With 95% of Americans owning a cellphone, it can feel like we’ve been calling, texting, and tweeting on the go forever. But the infrastructure supporting our cellphones has actually not been around that long. While we’re now on 4G networks, it was only 35 years ago today that Ameritech (now part of AT&T) launched 1G, or the first commercial cell phone network.

That network, called the Advanced Mobile Phone System (AMPS), went online on October 13, 1983, allowing people in the Chicago area to make and receive mobile calls for the first time. Ameritech president Bob Barnett, who made the first call, decided to make the historic moment count by ringing Alexander Graham Bell’s grandson. A little more than a year later, UK’s Vodafone hosted its first commercial call on New Year’s Day. Israel’s Pelephone followed suit in 1986, followed by Australia in 1987.

7 October 2014: There are officially more mobile devices than people in the world
The world is home to 7.2 billion gadgets, and they’re multiplying five times faster than we are.
The number of active mobile devices and human beings crossed over somewhere around the 7.19 billion mark.
