Samsung's 'Follow Your Instinct' campaign uses a new feature in YouTube called annotations: embedded links within videos allowing you to access other videos. Essentially, this allows people to choose your own path through a video increasing interactivity.
With almost non-existent promotion each video already has approximately 40,000 links. This demonstrates the need to monitor the development of new technologies - you could create a very innovative campaign.
