Simon Cowell's Britain's Got Talent delivers thrashing to Big Brother

Simon Cowell's Britain's Got Talent has helped ITV1 to thrash Channel 4's Big Brother in the ratings.

Britain's Got Talent premièred on Saturday with an audience of 4.8 million. The audience rocketed to 6.4 million on Sunday and grew again to 6.9 million yesterday evening. This was almost three times the 2.6 million who watched the latest developments in the Big Brother House.

The ITV1 series, hosted by Ant and Dec, will run for another six evenings.
