Point of Consumption
Licensing principle taxing/regulating gambling where the CUSTOMER is located, not where the operator sits.
The jurisdictional principle that gambling is regulated and taxed where the customer is, not where the operator sits. Britain's 2014 amendment made it mainstream; Sweden, Spain, the Netherlands, Ontario and most modern regimes are built on it.
Its consequence is the multi-licence reality of the industry: an operator serving five point-of-consumption markets needs five licences and five compliance stacks. It also defines the grey market from the regulator's side — serving customers in a point-of-consumption jurisdiction without its licence is what enforcement targets.
Britain's 2014 switch is the model case: before the Gambling (Licensing and Advertising) Act 2014, operators served British customers under whichever respectable licence they held — Gibraltar's, mostly. After it, anyone taking GB custom needed a British licence and paid British duty. The offshore hub model did not end, but its tax arbitrage against Britain did, and every major market built since has copied the principle.
Point of consumption is also why a modern operator holds a portfolio of licences rather than one: each POC market — Britain, Sweden, Spain, the Netherlands, Ontario — must be licensed separately, while a point-of-supply licence covers the grey remainder. The atlas's country pages are, in effect, a map of which rule applies where.
Point of consumption is arguably the single most important concept for reading this atlas correctly: the world map colours jurisdictions by the player's law precisely because that is the law that governs. Every 'regulated' marker implies a POC regime; every licence-portfolio fact on the operator side follows from it. The 2014 British switch is documented on the Gambling Act 2005 page as the template the rest of the column copied.
