Simon Cowell has taken to Twitter, providing a hint that the format of his hit TV show The X Factor will be tweaked.

Tweeting “Next year on our shows the rules change. I had a light bulb moment two weeks ago”, a change in format was expected, particularly in the UK where viewing figures are said to have dropped heavily over the past few seasons of the show.

The current series, which ended last week seeing Sam Bailey crowned as the winner, saw the lowest viewing figures for the final since 2005, as viewers switch off to having more media choices available.
