PlayStation 4 versus Xbox One: Rival consoles battle it out

The biggest names in gaming technology are going head-to-head in a battle to secure the top spot with games fans.

They are both releasing new devices - Microsoft's Xbox One goes on sale at midnight on Thursday while Sony's PlayStation 4 arrives in the UK next week.

Gaming is big business in Britain, with more than one third of the population playing some form of video game.
