This year's top video was "The Fox" by Norwegian parody-pop duo Ylvis, which racked up over 275 million views since its release in September. The song's viral success got the group their late-night debut on Late Night with Jimmy Fallon, an "SNL" parody skit featuring Kerry Washington, and a deal for a children's book.
"The Fox" wasn't the only mock music video to hit the list. "YOLO" featuring Adam Levine, Kendrick Lamar and comic Andy Samberg was number seven on the list, putting a pessimistic spin on the catchphrase acronym, "You Only Live Once," that was popularized by rappers Drake and Rick Ross.
The viral "Harlem Shake" meme was undoubtedly a notable phenomenon of the year, with the original army edition ranking second on YouTube's list with over 95 million views.
Other videos featured included a Chatroulette version of Miley Cyrus' "Wrecking Ball" by comedian Steve Kardynal, the Evian ad "baby&me," a coffee shop promotional stunt for the latest "Carrie" movie, and an ad for Volvo Trucks featuring Jean-Claude Van Damme doing an "epic split" between two moving trucks.
YouTube also released a list of Top Trending Music Videos featuring PSY's "GENTLEMAN M/V" at the top spot, as well as three videos by Miley Cyrus: "Wrecking Ball" and We Can't Stop," and "23 (Explicit)."
Other lists included top trending videos in news, education, pranks, sports and parodies.
