In the National Hockey League equivalent of hell freezing over, the Chicago Blackhawks will be — finally — regularly airing home games on local television.

And new team owner Rocky Wirtz encapsulates just why with this quote:

“As far as advertising, it’s pretty hard to sell dasher-board advertising when the only time you see it is the 10 o’clock news.”

That’s part of the sell when it comes to the already-lucrative business of arena advertising: Guaranteeing plenty of rapt viewers. The wonder is how this concept eluded Rocky’s dad, the late Dollar Bill Wirtz, for so many years.
