You weren't the only person to waste a lot of time on YouTube this year. In March, the video giant reached 1 billion monthly unique visitors. Altogether, over 6 billion hours of video -- a 50 percent increase over 2012 -- were watched each month.
But what exactly entertained us during all those late nights in front of the computer? To cap off the year, YouTube released a tribute video (above) to its viral stars -- including Mystery Guitar Man, Overly Attached Girlfriend, Annoying Orange, and a herd of stampeding goats -- and ran down the year's most popular videos.
YouTube broke videos into two categories: Music videos, which get the lion's share of views on the site, and everything else. Below, we run down the latter; for music video, check out the list here.
"Mozart vs Skrillex. Epic Rap Battles of History Season 2"
