Dive Brief: 

• During the NCAA college football championship Monday, Marvel teased its trailer for the new Avengers movie, which may help settle the battle between YouTube and Facebook video. 
• Marvel uploaded the clip directly to both YouTube and Facebook and attracted 12 million views in less than 24 hours. 
• Over time, YouTube pulled ahead with 7.5 million views versus Facebook's 5.4 million—proving that YouTube's staying power may keep it as the leader for brand videos. 

Dive Insight: 

For a long time, YouTube has ruled the brand video space, mostly because of a lack of real competition. Facebook's video, along with its autoplay feature, are stirring the pot when it comes to marketing—at the end of 2014, Facebook passed YouTube in the number of brand videos uploaded. What the Avengers trailer shows is that while Facebook has its advantages—autoplay, easy sharing, etc—YouTube gives the video a longer shelf life. Perhaps the secret will be to include both platforms in brand video strategy.
