Also Marketplace airs on NPR stations. I have Windows on a Dell, and I hear Marketplace on NPR.
The local stations mostly call themselves NPR stations (NPR member stations) and they explicitly include NPR branding (ex - right in the logo for mine: https://www.wabe.org/) and pay membership dues to NPR in addition to content licensing.
APM also has its own set of stations, but the list is much smaller. Plus - basically the only content from APM on my NPR station is Marketplace.
It's "NPR" for all intents and purposes. It's not dual booting, it's like a linux machine running WINE for a single application.
