Casey Newton reports on The Verge that Netflix is testing interactive video with half its audience — kids.

The first title is Puss in Book: Trapped in an Epic Tale.

Carla Engelbrecht Fisher, Netflix’s director of product innovation, says:

“Kids are already talking to the screen. They’re touching every screen. They think everything is interactive.”

The result is a branching story that results in varying viewing lengths of 18 to 39 minutes.

A second title will have a simpler structure with four endings:

Note that Netflix has not invented branching stories — Choose Your Own Adventure published 250 million gamebooks over two decades in the previous millennium.

My take: it’s interesting that Netflix only has the technology working on half of their platforms. Nevertheless the potential is seductive. Think of the dramatic possibilities: “Feeling lucky, punk?” or “You take the blue pill—the story ends, you wake up in your bed and believe whatever you want to believe. You take the red pill — you stay in Wonderland, and I show you how deep the rabbit hole goes.” One thing writers will have to get used to is the cavalier ease at which the audience will be able change the narrative — kind of like print designers had to let go of exact specificity when the web came along.
