YouTube has released its list of the top ten viral videos of the year.  Number one is "Gangnam Style"....duh?   it's been viewed almost a billion times.

--A few other notable videos on the list are the Kony 2012 video, which was number three . . . Carly Rae Jepsen's video for "Call Me Maybe", which featured Justin Bieber . . . and Felix Baumgartner's 128,000-foot skydive

YouTube released its annual "Rewind" video....which is pretty cool...I like that they mash-up  "Gangnam Style" and "Call Me Maybe."  ...check it out...
