The Britain’s Got Talent final is poised to become the most popular programme of the year – unless big-hitting programmes such as Doctor Who and Strictly Come Dancing can beat it.

Viewing figures showed that ITV1 boasts the top programme on any channel in 2009, with 18.3 million fans tuning in to see street dancers Diversity triumph over Susan Boyle (pictured) in a shock victory on May 30.

The show, which propelled Su-Bo to global stardom despite coming second, drew a 68.1 per cent audience share and became the top programme on any channel since June 2006, when 18.5 million people watched England battle Sweden in the World Cup.

ITV1 also has six out of the top 10 programmes on any channel this year, with The X Factor results show on November 15, which saw Jamie Archer eliminated, taking second place with 15 million viewers and a 48.4 per cent share.

The figures, provided by ITV, are for the period up to November 29 and so do not take into account Sunday’s X Factor final, which is said to have averaged a live audience of 15.5 million.

BBC1’s Strictly Come Dancing has been lagging behind The X Factor in this year’s viewing figures, but hopes will be high for strong figures as the series reaches its climax this weekend.

Doctor Who’s adventures over the festive season, which will see David Tennant bow out in tear-jerking scenes, are also set for massive success for the BBC, with the first of two specials, The End of Time, Part One airing on Christmas Day.
