It is reported that online singing sensation Rebecca Black topped a 2011 most-viewed YouTube videos list. The latter included spoofs starring pets, talking babies and pop music star Michael Bolton.
The collection of the year's most popular YouTube snippets was based on an analysis of the more than one trillion video views logged at the Google-owned website.
"That's about 140 views for every person on the Earth," YouTube trends manager Kevin Allocca said in a blog post. "More than twice as many stars as in the Milky Way."
The world's most watched videos in an array of categories from news to politics or major music labels were online at youtube.com/rewind.
Images of tsunami waves triggered by the devastating earthquake in Japan was the top news video shared at YouTube during the year, while a buck attacking a bicyclist led in the sports category.
The most watched "how-to" video showed 25 ways to wear a scarf in 4.5 minutes.
