Define a "huge market". lol Phoenix and Atlanta are huge markets, the Islanders are in a huge market.
Yes, and when those teams were under stable ownership their corporate income was a huge part of their profit line. Arguably, the Thrashers' sole
raison d'etre at this point is to maintain suite prices for their umbrella organization that includes the Hawks. Similarly, I'm sure the City of Glendale is interested in keeping the Coyotes in town at least in part because their corporate relationships have an effect on local businesses and the economic value of the arena. I'm not as familiar with the situation in Nassau, but from what I understand it lacks suites so the point is moot.
Come to think of it, the Thrashers may never have even existed if it hadn't been for Ted Turner's octopus-like corporate reach in Atlanta.
Compare those organizations to the Predators, who have a relatively strong grassroots fanbase but lost money due to weak corporate support in the Nashville market. Part of that was their own doing, but part of it is the difference between having eleven Fortune 500 headquarters (Atlanta) versus only two (Nashville).
