Ad Age lists the top 10 viral videos for the week of March 15 based on viewer tracking by online video firm Visible Measures.

 

Of this week s four new entries, three broke into the top five. Ad Age says Doritos seems to have a working formula for viral videos, placing its second number one on the chart in two months with a video promoting a contest in Canada that drew more than 2.3 million views. The winning formula here could be the scary puppet. A little further down at number three, Sony s long-form ad for PlayStation Move that took a few stealthy swipes at Microsoft’s Xbox 360 motion controller debuted on the chart with nearly 1 million views. It’s worth noting Microsoft’s Natal video is still on the chart at number nine with about 460,000 views, its 39th week on Ad Age’s top ten. The remaining new entries are two hilarious college humor themed virals. Muscle Milk’s take on spring break was the fourth most viewed on the chart with about 866,000 views, and Capital One’s long video spoofing a March Madness Cinderella story entered at number six with 530,000 views.  Check out the full list and watch the videos at Ad Age.
