According to Visible Measures, which tracks videos from YouTube, MySpace and other video-sharing sites, Boyle’s audition has generated 66.3 million views. On YouTube alone, it’s been viewed more than 30 million times. The 7-minute video that was posted on YouTube last Saturday and then widely circulated online easily eclipsed more high-profile videos that have been around for months. Tina Fey’s impersonation of Sarah Palin has clocked in 34.2 million views, said the folks at Visible Measures, while President Obama’s victory speech on election night has generated 18.5 million views. In less than a week, Boyle topped them.
