2003: the year in technology
It was the worst year in history for computer worms and viruses. The trouble began in January when the highly contagious Slammer worm infected a quarter of a million computers in just a single day. The following months saw further outbreaks with the viruses Fizzer spreading via both email and file-sharing networks in May and Bugbear attempting to steal passwords and other information from victims in June.
The most striking use of technology came in March when the US and allies went to war in Iraq. The conflict was characterised by unprecedented use of smart bombs, cruise missiles, satellite surveillance and hi-tech propaganda, highlighting the military's growing reliance on technology.
The year ended with a celebration of the centenary of manned flight. Researchers at Boeing Phantom Works and DARPA revealed what the next hundred years may deliver, including personal air vehicles and morphing aircraft.
