The 10 Most Watched Ads on YouTube in May

Nothing can stop the marauding hordes of Clash of Clans ads, judging by this month's YouTube Ads Leaderboard from Adweek and Google.

Three spots from Barton F. Graf 9000 for the Supercell game sweep the top three places on this month's list of most-watched commercials on the video site. And another Supercell game, Boom Beach, places two more ads on the list—giving Supercell fully half of this month's spots.

Delta, Coca-Cola and KFC also managed to squeeze their way in, as did an introductory spot for the Lily camera—"the world's first true flying camera." See all 10 spots below.

Note: To be eligible for Adweek and Google's YouTube Ads Leaderboard, videos must be marked as ads on YouTube (i.e., they get some paid views) but must also earn significant organic views.
