Nit: Marketplace is an APM show--essentially a competitor of NPR. "NPR" has just become shorthand for "public radio."
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.
I happen to listen to Marketplace on NPR, not Marketplace by NPR.
