There's a network called K-Love that broadcasts contemporary Christian music across the United States[1]. It's the same programming in every market, apart from the occasional regional flavor in advertising and/or pledge drives.
I didn't search to confirm this, but I'm pretty sure that federal regulations prevent fully syndicated radio stations across markets, but they don't apply to nonprofits. That's why you'll have an iHeartRadio Top 40 station in every metropolitan area but they all have their own talent.
Yes, well there are many different networks that are syndicated everywhere. The question is if they could control the same frequency everywhere, which I don't think makes sense with how our radio stations are structured.
Just as banter, what other networks are syndicated everywhere? I drive a fair bit and will hear K-Love and NPR everywhere. Sports talk will sometimes syndicate later at night, and of course the political talk stations will have programming from elsewhere. But apart from the Christian stuff, I've never heard music syndication as I go between markets.
Well the biggest ones are on AM, though they seem to be starting to cross over to FM more recently. So Premiere Networks, Salem etc... all syndicate the conservative talk guys and things like Coast to Coast AM.
By the way Coast to Coast AM with Art Bell is how I got into radio in the first place and was probably the widest reaching single AM show worldwide.
