"Should be" is perhaps a correct statement. But they won't be.
All the girls' tournament coverage is still on IPTV, but the IHSAA wants more money. So they created the IHSSN (Iowa High School Sports Network) as a production entity, and then sell their coverage to media outlets. It used to be they'd just let individual TV stations around Iowa buy the telecast, but that wasn't enough $$$, so they sold the rights to NBC Sports Chicago. Your cable company doesn't carry them? Tough. You live in western Iowa where you have no interest in a Chicago cable sports channel? Too bad for you.
This goes for radio, too. If your local radio station covers semifinal/championship games in the Dome, they have to pay a rights fee to the IHSSN. And it's a significant amount, too. There are some media TV/radio dollars rolling into Boone this time of year ...
