If you want to advertise at the World Series of Poker (WSOP), you have to compete with hundreds of brands and pay astronomical fees for a tiny hallway booth.
But what happens when the circuit moves to mid-tier regional stops, local championship fields, or high-volume multi-day events across the US and Southeast Asia?
Casinos don't have the space, the infrastructure, or the desire to host vendors for fields of several hundred players. For advertisers, these rooms are a complete black hole. You cannot buy billboard space next to the tables. You cannot set up a table in the lobby. The casino floor is completely locked down to outside corporate eyes.
