One year and 70 million views later, the Nyan Cat celebrates it's YouTube birthday today. The backstory is easy enough to explain: animated gif plus Japanese pop tune equals weird looped animation. What happened after is anything but.

Defying the logic of many, the clip went on to become one of YouTube's top 10 most-viewed videos of 2011 and spawned seemingly countless parodies, remixes, and covers. There is a 100 hour version now. With 6 million views.

Interestingly, while the video did see an initial spike in interest in April of 2011, it was not as large as some of the other well known viral hits. Instead, a look at the data shows that the clip has maintained a fairly steady following, averaging around 1 million views per week over the past year.



In the neighborhood of 100,000 videos have been posted with "nyan" in the title over the past year. And those videos have been seen over 400 million times. 400 million. Nearly half a billion.
