For people who still watch regular broadcast television, it has become very common to actually watch TV while simultaneously using your laptop, phone, or tablet. Savvy networks like USA/NBC have picked up on this and created gamified mobile companion applications to engage with users as they both watch TV and browse on the net. There are compelling case-studies that outline the efficacy of this concept, coined the second screen, but I have not really seen any other kinds of engagement tactics for viewers. However, I found inspiration for new possible ways from the gamer community, and more specifically, the Dota 2 community.
