While the first YouTube video was uploaded nine years ago on April 23, 2005, the site went live in May. So to celebrate the anniversary, the video-sharing network has released a music mashup featuring various YouTube celebrities.
Frozen fans will be excited to learn that, according to data from YouTube, "there are more than 120,000 videos inspired by “Let It Go" (based on videos posted with that title)." Not to mention there are "half a million by 'Gangnam Style,' and a stunning 1.5 million videos by 'Harlem Shake,'" in case you thought those memes were dead.
