The trend of the long form ad is catching on. I love the limitless possibilities of creating video that's longer than 30 seconds. Here are great examples of long form (branded content, call it whatever you want) ads that are very successful:
Gatorade's "Replay" by TBWA/Chiat Day
Chanel's "Remember Now" by Karl Lagerfeld
