HBO Announces iOS App-Based TV Show 'Mosaic' With Branching Narrative and Multiple Endings

HBO recently announced a new TV project in the works by director Steven Soderbergh called "Mosaic." The show will air as a six-part linear narrative in early 2018, but in addition to the traditional distribution, HBO is launching an app where viewers can watch the show, make decisions, and help shape the outcome of certain events (via The Verge).

The Mosaic iOS app will be available to download for free beginning in November, and it will let viewers choose what point of view they want to follow the story, effectively building their own experience from material written and directed by Ed Solomon and Soderbergh, respectively. According to HBO, each choice "builds upon one another," leading to different versions of the same scene, and different endings.

“MOSAIC is a branching narrative piece. While branching narratives have been around forever, technology now allows, I hope, for a more elegant, intuitive form of engagement than used to be possible. Also, we weren’t reverse engineering the story to fit an existing piece of technology; the story was being created in lockstep with the technical team. The fluidity of that relationship made me feel comfortable because I wanted it to be a simple, intuitive experience. I didn’t want moments where you are making a decision to feel like interruptions.”

In both mediums, the show will star Sharon Stone, Garrett Hedlund, Beau Bridges, Paul Reubens, and others. The iOS app will include character profiles and various pieces of content -- like newspaper clippings and voice recordings -- that serve to deepen the show's story. The plot itself is largely being kept under wraps by HBO and Soderbergh, but is expected to have some murder mystery elements.
