“Second Screen Business for Operators” provides insights about the business operators can develop on second screen applications. Based on the second screen white paper “Decrypting the Second Screen Market”, this paper presents briefly the second screen application market and describes how operators can be positioned on this market (including SWOT analysis). Operators can be positioned on TV Discovery Applications to increase their sales by making users consume more content on their platform through effortless TV discovery (recommendation, smooth browsing, user-friendly interface…). This type of applications can be launched quite easily and have positive impacts quickly. They can also be positioned on Social TV Applications to increase operator content value and gain new clients with worldwide consumer analytics. Operators would then choose to diversify their offer.
