FanDuel Sports Network (FDSN) is a local sports media platform. Making up the largest portfolio of local sports rights in the United States, the company broadcasts thousands of live regional games from the NBA, NHL, MLB, WNBA, PWHL, Athletes Unlimited, and more. Their coverage spans 15 networks and 14 major U.S. markets, offering both traditional linear cable broadcasts and a direct-to-consumer (DTC) service to keep fans connected wherever they choose to watch their favorite teams.

In 2022, FDSN (then Bally Sports) decided to move their digital infrastructure away from a third-party platform and instead develop an owned-and-operated system that they could manage in-house. With our extensive experience across mobile and Connected TV platforms, along with our ability to build reliable, scalable back-end platform software, Mercury was the ideal partner for this project.

Key Considerations

Third-Party Integrations

Although the platform solution and client applications were custom-developed, our system required integration of many dependencies from third-party providers, including video production services at the stadium and authentication and subscription management.

Live Game Traffic

The nature of live sporting events means that most user traffic happens all at once, as thousands of fans sign in to watch their teams, along with fans in other markets whose teams are playing at the same time. Therefore, the system had to be capable of handling large bursts of concurrent traffic when as many as ten teams might all have games starting during the same time period.

Regional Watch Restrictions

Contractually, a lot goes into determining whether a fan can watch a game. What region are they currently in? What ZIP code is linked to their account, and does it match the team they want to watch? Do they have an active subscription? The business logic involved in tailoring content for each user in each region is extremely complex, and our systems need to be flexible enough to accommodate a modern DTC offering within the traditional RSN model.

Results

The FDSN platform manages all direct-to-consumer needs within its complex RSN structure. Mercury built a scalable backend capable of supporting tens of thousands of concurrent viewers as games across multiple sports are streamed. During April and October, when MLB, NBA, and NHL all have active game windows, there can be as many as 20 overlapping game schedules. The system we created for FDSN can handle this scale without any interruptions.

Additionally, our flexible middleware API layer seamlessly connects all integration points, from video providers and advertising partners to authentication, subscription services, and game data such as scores, schedules, and more. The system is also designed to adapt in real-time, adjusting game windows as needed when unexpected events like rain delays or multiple overtimes disrupt scheduled times. Of course, our client applications—whether on phones, tablets, TVs, or desktops—ensure the content experience is smooth and user-friendly, giving fans easy access to the content they want most: the game.
