The Ads Leaderboard highlights branded video ads that consumers choose to watch. In this edition for the first half of 2017, we meet brands that leverage YouTube as the video platform to share their story with the audience. As in previous leaderboards, we observe that users are willing to watch ads of longer duration, with 6 out of 10 videos being longer than 2 minutes. Moreover, we see how brands like Kit Kat and Maybelline utilize the influence of YouTube Creators to amplify their message, and make their users part of the brand story.
