The mobile phone turned 40 on Wednesday, with no fanfare to mark the occasion in a market that 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 working on mobile communication technologies. Cooper made the call on Sixth Avenue in New York, before going into a press conference using a Motorola DynaTAC - a device that weighed 1 kg, and had a battery life of 20 minutes, according to Motorola.
Cooper told the technology website The Verge last year that he placed the first call to a rival, Joel Engler of Bell Labs.

Cooper and his team were honoured earlier this year with the Draper Prize by the National Academy of Engineering for their work.
In 40 years, the industry has come a long way. Research firm IDC predicts 900 million smartphones will be sold in 2013 - along with roughly the same number of more basic feature phones. And the phone has become a key advertising platform - eMarketer said the US' mobile advertising spending had grown 178 per cent last year to $4.11 billion, and spending was expected to rise a further 77.3 per cent to $7.29 bn in 2013.
