The channel has hit one billion views, which makes it the most watched YouTube channel for a British television series ever.
It is no surprise that SuBo made the five most watched clips since the channel launched three years ago, but there are also some more unlikely appearances.
Ten-year-old schoolgirl Natalie Okri, who told the BGT team she wanted to be a "singer and a diva", wowed the judges when she sang an Alicia Keys song
And she's the standout star of the BGT YouTube channel, as her 2009 audition has been watched 54 million times.
Controversial young singer Ronan Parkes also racked up the views, despite claims that the 13-year had been known to Cowell's firm, Syco, for two years prior to his audition.
Michael McIntyre told Ronan, "You said you'd taken a day off school, I wouldn't bother going back," and although his audition has been viewed online almost 20 million views it seems the talented kid has headed back to education.
Perhaps most surprising in the top five is Mr Methane, who describes himself as a "performing flatulist".
Despite Amanda and Simon hitting their buzzers just seconds into the audition, then-judge Piers Morgan held off to find out what the parpy performer had in store.
Simon Cowell was not impressed and branded Mr Methane a "disgusting freakshow", but 22 million people have watched him turn embarrassing bodily functions into something resembling music.
London-based dance troupe Diversity also attracted around 21 million online viewers with their winning performance in the show's 2009 final.
While this year's runners-up, Jonathan & Charlotte, are already the eighth most watched video, clocking up 18 million viewers with their audition for the judges.
Theo Luke, Head of Digital at Syco Entertainment, said it was a "landmark achievement".
"We want viewers to enjoy our shows wherever they are and YouTube is a magnificent platform to reach them."
