Mobile phone turns 40, with little fanfare
The mobile phone turned 40 on Wednesday, with no fanfare to mark the occasion in a market which seemed focused on new smartphones like the iPhone and a possible Facebook-themed device.
The first mobile call was placed April 3, 1973, by Motorola engineer Martin Cooper, head of a team
"To this day, he resents what Motorola did in those days," Cooper said.
"They thought that we were a gnat, an obstacle... we believed in competition and lots of players. And we also believed -- our religion was portables, because people are mobile. And here they were trying to make a car telephone and a monopoly on top of that. So that battle was the reason that we built that phone."
Cooper and his team were honored earlier this year with the Draper Prize by the National Academy of Engineering for their work.
And the phone has become a key advertising platform -- eMarketer said US mobile advertising spending grew 178 percent last year to $4.11 billion, and spending is expected to rise a further 77.3 percent to $7.29 billion in 2013.
