There are millions of videos on YouTube. Some of them I’ve featured as part of the A Year of YouTube series are ones you may have seen yourself. Some you may have seen for the very first time. You’d like to think that you’ve heard of all of the popular videos that have millions of hits. In this case my first experience with Keenan Cahill was during his appearance on NBC’s America’s Got Talent a few weeks back during the YouTube special results show. Apparently he has in fact received millions of hits, nearly 300 million at the time of this article. He performs in his bedroom, lip-syncing to a number of songs. His “take” on Katy Perry’s “Teenage Dream” is his most popular receiving nearly 45 million views so far. His popularity has reached the heights that even 50 Cent has appeared in one of his videos. Of the few Keenan Cahill videos I’ve watched, he appears to not know some of the words at times. Whatever it is that people enjoy about him has certainly caught on, millions of times over.
