The 10 most effective ad campaigns this year

Online advertising service Warc has released its 2016 rankings of the world's 100 most effective advertising campaigns.

This year, online campaigns dominated the top 10. 11 of the 20 highest-ranked campaigns were digital-led. Ad firm Droga5 was the only agency to get into the list more than once. It featured three times with campaigns for Under Armour, Honey Maid, and Newcastle Brown Ale.

The campaigns were ranked according to a points score calculated with a "rigorous methodology" using data from ad award ceremonies around the world. The assessment included the campaign's impact, industry perception, and the level of competition it faced. For each competition a particular campaign won, its award points were multiplied by the rating of the competition.
