The 10 Most Watched Ads on YouTube in January

Bernie Sanders and Ted Cruz crashed Adweek and Google's YouTube Ads Leaderboard in January, ranking the most-viewed ads on the video site, and a PAC's anti-Donald Trump spot also made the top 10—as Election 2016 began to heat up.

Sanders finished highest on the Leaderboard, with his well-received "America" spot finishing at No. 5. The Cruz and anti-Trump ads clocked in at Nos. 9 and 10, respectively.

Gaming spots took the top four slots, and Supercell (and its agency Barton F. Graf) once again dominated—with Clash of Clans ads finishing at Nos. 1 and 2 and a Boom Beach spot at No. 4. In between was Pokémon's 20th anniversary Super Bowl commercial.

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. The algorithm factors in paid views, organic views and audience retention (how much of a video people watched).
