Looking back, it may have been the most important phone call in technology history.

On April 3, 1973, inventor Martin Cooper made the first known call on a mobile phone using a prototype Motorola DynaTAC, Forty years later, it's considered a brick compared to the tiny devices we carry around.

The call took place in New York City. Cooper's inspiration for the phone was Captain Kirk's famous flip-top communicator from the Star Trek series.

The original DynaTAC was 10 inches in length and weighed 2.5 pounds, a behemoth by today's standards. For comparison, most modern smartphones weigh between 4 and six ounces.

Today, Cooper helps run the tech incubator Dyna LLC. He also works as an advisor for companies and the government on telecommunications issues.

Cell phones are everywhere in 2013. According to the U.N., the world has 6 billion cell phone subscribers. And more of them are moving into the realm of smartphones. Last fall, the tech research firm Strategic Analytics claims the global smartphone population topped 1 billion.
