A Facebook study has revealed that Twitter might have a battle on its hands as the social network of choice for real-time engagement while people are watching films or TV. The research is the result of a partnership between Facebook and UK analytics firm SecondSync, and looked at social TV data from the US, Australia and the UK. As you might expect, a majority of TV-related interactions (80 percent) on Facebook were made via a mobile device – the classic ‘second screen’ scenario – but perhaps more surprisingly, 60 percent of interactions happened while the show was still airing. This finding sits contrary to the notion that Twitter is the go-to social network to discuss a show while it is airing, while Facebook is the place to discuss it in more detail, usually once it has finished. While the study looked at many facets of interaction, it also focused on how users were engaging while watching TV.
