Youtube user SMPfilms’ video series has made an online version of "Choose your own adventure". The adventure utilises the video response system in YouTube to make online video into a game of sorts. Users watch the first clip and then make their choice on what should happen next in the story, in exactly the same vein as the book version.
Below is the first in an adventure about someone trying to find his cat. In order to participate in the story, you'll need to watch the clip on YouTube. Perhaps not the most exciting premise for a story, but still an interesting idea to increase the level with interactivity for brands utilising such channels.
