The reference
Nine sectors sit between a gambling licence and a game on a screen. Each entry records what the company does, where it sits in that chain, when it was founded, how it is owned and which brands it is known for.
The industry is far more specialised than its public face suggests. A player sees a brand and a game; behind them are a platform running the accounts, an aggregator supplying the content, a studio that built the game, payment providers moving the money, a data company pricing the sport, a laboratory that certified everything and, frequently, an affiliate that sent the customer.
Entries are not advertisements and cannot be purchased. Companies appear because they occupy a position worth recording, and the text describes what they do rather than how well they do it. The supply chain is explained here.
