Britain’s Got Talent star Susan Boyle has proved the year’s biggest hit on internet video channel YouTube.

The unlikely singing sensation mesmerised the world with her rendition of I Dreamed A Dream on Britain’s Got Talent, and ended up taking second place in the ITV talent show in April 2009.

But no one came close to outshining her on YouTube, with Su-Bo’s videos attracting more than 120 million views worldwide, more than the next three most-watched videos combined.

A movie trailer for The Twilight Saga: New Moon also made the top five, attracting 31 million views.

Others on the list – which marks the first time that YouTube has ranked its most-watched videos in any year since its 2005 inception – included a bride and groom dancing down the aisle and roller-skating babies.

YouTube compiled a separate list of the year’s most popular studio-produced music videos.

Rapper Pitbull’s I Know You Want Me was the category’s top draw with more than 82 million views, trailed by two music videos by Disney star Miley Cyrus, The Climb (more than 64 million views) and Party In The USA (more than 54 million views).

Michael Jackson, whose shocking June 25 death made him the most searched subject on Google this year, also left his mark on YouTube in 2009.

His name topped YouTube searches during the months of June and July and his 27-year-old music video Beat It logged more than 25 million views.
