Interactive TV shows have previously been dismissed as a gimmick, but now two big names are getting involved: Steven Soderbergh (director of 'Ocean's 11') and HBO, the critically-acclaimed US TV network.
Soderbergh's new mini-series 'Mosaic' will let viewers interact with it via a smartphone app. Using the app, viewers can jump into a character's head and see what they're thinking. You make choices within the app, the outcomes of which can produce a different ending for the episode you watch.
According to Soderbergh, the show was developed with the app in mind, so it's not just an afterthought.
The interactive devices include character profiles, newspaper cuttings and voice memos.
The show will star Sharon Stone, Garrett Hedlund, Frederick Weller, Beau Bridges and Paul Reubens. It will air in January in the US, but the app will be available from next month.
"While branching narratives have been around forever, technology now allows, I hope, for a more elegant, intuitive form of entertainment than used to be possible," said Soderbergh.
HBO isn't the only one dabbling in interactive storytelling. Earlier this year, Netflix launched a range of interactive kids' shows.
