On September 22, 2011, Showtime launched Showtime Social, a second screen interactive app providing interactivity with Showtime programs including viewer-participant polls and trivia questions as well as real-time aggregation of Twitter, Facebook and blog comments about particular Showtime programs; the app utilizes Automated Content Recognition technology to generate interactive content regardless of whether it is being watched live, on-demand or by DVR; the app also displays heat maps depicting viewer reactions throughout the duration of an episode at the conclusion of the program. The app – which was renamed SHO Sync on September 13, 2012 – was originally released for Apple iOS devices (iPad and iPhone), with an app for LG-manufactured Smart TVs being released on August 15, 2013.
