Rebecca Black’s infamous ‘Friday’ video has topped all other YouTube videos of 2011 with 180 million views.The Google Inc. video-sharing site announced its most-viewed clips of the year. The 14-year-old Black was turned into a viral video celebrity after her parents paid a production company to make the music video for her. ‘Friday’ became an unlikely, off-key global hit. Because of a legal dispute with Ark Music Factory, the video has had two YouTube incarnations, both of which were tabulated in the year-end count. The second most popular video was ‘Ultimate Dog Tease,’ in which an owner taunts a dog with food and voices its reactions. Third was the ‘Saturday Night Live’ digital short featuring Michael Bolton as a rabid ‘Pirates of the Caribbean’ fan.
