Science Museum exhibition explores the 'information age'

One of the most ambitious projects ever undertaken by the Science Museum has been opened by the Queen in London.

The Information Age gallery, which has taken three years to plan, takes visitors on a journey through the history of modern communications, from the telegraph to the smartphone.

Exhibits on show at the gallery include the first transatlantic cable which connected Europe and North America, the broadcast equipment behind the BBC's first radio programme in 1922, and Sir Tim Berners-Lee's NeXT computer, which hosted the first website.

The BBC's Rory Cellan-Jones takes a journey through The Information Age.
