Ad agency Wieden + Kennedy has taken the top honours in YouTube’s creative agency leaderboard for agencies that best used video content in 2015.

TBWA’s Media Arts Lab came second with silver, with Barton F. Graf and GoPro Original Productions tied for bronze.

The list celebrated the agencies that had the most number of ads appear on YouTube’s creative leaderboard list each month. The ads that are included on the list are compiled from a YouTube algorithm. The algorithm “factors in organic and paid views, watch time and audience retention”.

Wieden + Kennedy’s work appeared eight times on the leaderboards throughout the year. TBWA’s appeared seven times and Barton F. Graf’s and GoPro Original Productions both appeared six times.

In the year list Weiden + Kennedy’s work for FIFA and its Play Beautiful commercial was the top ranked ad for the year.

Second ranked for Weiden + Kennedy was Pepsi Max’s ‘Uncle Drew’.

Other pieces of work which appeared were KFC’s Address, Old Spice’s And So It Begins and The Internetest Safety video on the internet.
