Ignoring the pragmatic, WSM is considered a cultural institution by many. Were Ryman to announce such a move, I suspect it would see the same outcry as when they planned to switch programming to all sports in 2002. Even George Plaster's 2019 attempt to add sports talk in afternoons lasted only a month.
Yes, I know. Covid, et al. Things have changed since then. But this is Nashville. That Blaw Knox tower could just as well be the Eiffel in the minds of the Nashville music elite. For crying out loud, the thing is even represented in the exterior design of the downtown Country Music Hall of Fame.
I'd sooner expect Ryman (and always remember where Ryman Hospitality got their name) to first do the same as what iHeart did with the WLW Mason, Ohio transmitter site. Develop the land around the tower and transmitter building. Of course, WLW remains an 11 share radio station. Yet as historic as WLW is, it's arguably not of the same historic value as WSM and its Opry.
I've often pondered if putting WSM into the hands of the Country Music Hall people is the future for AM 650. Just like the museum, Hatch Show Print and RCA Studio B facilities.
One other thing to remember. WSM's Brentwood site has been on the National Register of Historic Places since 2011.
