In Cleveland, the primary PBS and NPR stations were long separate (WVIZ/25 and WCPN/90.3), until merging under one umbrella (there's your rain protector - "ideastream", complete with lower case I).
In the Akron/Canton end of the region, the PBS affiliate (Western Reserve PBS/WNEO-45/WEAO/49) and the NPR affiliate (WKSU/89.7 and its simulcasters) share a link with Kent State University, but they're not "co-owned". KSU owns the radio station(s) outright, but is just one third of Northeastern Educational Television of Ohio, the consortium which runs the entity now known as Western Reserve Public Media.
The other thirds of NETO/WRPM are two other big public universities in the region, the University of Akron and Youngstown State University. Both have their own non-comm/public radio outlets, WZIP/88.1 and WYSU/88.3, which are not at all connected with WKSU - aside from an agreement that WKSU is now doing local news updates for WYSU.
Now, to scroll back and see what any of this has to do with KGO...
