Data Sourcing Methodology

Our Data Collection & Verification Process

WhereSports employs a multi-layered editorial approach to data collection, cross-referencing official league press releases, territorial rights registries, and verified broadcaster manifests to ensure absolute accuracy in sports scheduling and carriage information.

Primary Verification Sources

Official League Press Rooms & Rights Registries

Our editorial desk monitors primary distribution announcements from major sports federations and their authorized global distribution partners, including:

  • Global Football: UEFA, FIFA, and domestic league media guides (Premier League, LaLiga, Bundesliga).
  • North American Leagues: Official NFL, NBA, MLB, and NHL broadcast distribution grids.
  • Combat Sports & Motorsport: Official UFC, DAZN, and Formula 1 global territory mapping.

Broadcaster Carriage Manifests

We do not guess where a game is airing. We verify carriage directly against the published electronic program guides (EPGs) and digital manifests of authorized rights holders:

  • Linear network schedules (ESPN, Sky Sports, TNT, CBS, FOX).
  • Direct-to-consumer app libraries (DAZN, Peacock, Paramount+, Apple TV).
  • Regional Sports Network (RSN) territorial blackout maps.

Editorial Verification SLA (Service Level Agreement)

Tier 1 Match Verification

Marquee fixtures (NFL, EPL, Champions League, NBA Playoffs) are manually cross-referenced against network EPGs minimum 4 hours before kickoff.

Schedule Change Detection

When a network shifts a broadcast window for television reasons, our automated manifest scrapers detect the change and update the directory within 15 minutes.

Blackout & Geo-Fencing Checks

Every streaming app is tested against regional IP restrictions to ensure we only list platforms that legally hold the rights in the user's specific territory.
