2010 saw more likes, hits, tweets, and retweets than ever before. As media giants like Twitter and Google release their most popular searches and trends of 2010, Global News takes a look at the viral powerhouses in the entertainment world that defined 2010 online.

Bieber Fever

Tweens worldwide will likely not be surprised to learn that Canada’s pre-pubescent heartthrob Justin Bieber topped the list of, well, everything this year.

The Biebz ranked number one on Twitter’s list of Top Trends for people, earning him the eighth spot overall.

Google’s Zeitgeist 2010 lists Bieber as the number one search for both people and music in America, as well as the fastest rising search term under entertainment globally.

YouTube divides its top videos of 2010 into two categories: videos from major record labels, and independently produced videos. Justin Bieber’s “Baby” ranks number one for the most watched major record label video, with 408,450,994 views and counting.

The Bed Intruder

Never before has a story about an attempted rape garnered so much love and attention.

The news story-turned-YouTube sensation has earned its protagonist Antoine Dodson fame that would make the folks at Old Spice green with envy.

The original Bed Intruder Song is YouTube’s most watched video for 2010. The song also inspired remixes and remakes that earned thousands of YouTube hits in their own right.

The Old Spice Man

Speaking of Old Spice, the Old Spice (The Man Your Man Could Smell Like) video didn’t fair too poorly on YouTube either, placing fifth on 2010’s most watched list.

The original video received so much positive feedback that actor Isaiah Mustafa, the Old Spice Man himself, starred in subsequent ads, gathering questions from fans on Twitter and Facebook, and posting the answers on YouTube.

The videos can be attributed to not only reviving the aging deodorant company but also for shaking up the marketing world. Listed as one of the top marketing moments of 2010 the Old Spice ads redefined the power of viral advertising.

2010 at the movies

Christopher Nolan’s mind-bending juggernaut Inception earned $62,785,337 USD in its opening weekend. The film was the number one Twitter trend for movies, and placed third overall.

Placing right behind Inception for top Twitter trends in movies was Harry Potter the Deathly Hallows, which finished as the ninth biggest Twitter trend of the year.
