YouTube turns 9 today! The 9 most influential YouTube videos...

[Sookie]

Nine years ago today, YouTube co-founder Jawed Karim uploaded the very first video to his new site. It was an 18-second clip entitled Me at the Zoo.  It's a wholly unremarkable span of footage in which he points out that the elephants behind him have really, really, really long trunks. Today, 100 hours of video are uploaded to YouTube every minute. Kids who grew up with the Internet recall particular YouTube videos the same way their parents fondly remember their favorite Saturday-morning cartoons. To pay tribute to the website, we honor the most influential YouTube stars of our time. Though they might not have much in common aside from the medium where they launched to fame, they've been united by the serendipity of Internet virality.Be warned: Some of these videos contain adult language.You can view the 9 most influential videos <a href="https://www.yahoo.com/tech/for-youtubes-9th-birthday-here-are-9-of-the-greatest-83556987977.html" >here</a>
