For what reason did WABC remain important on AM radio?

Let me clarify-are you asking about WABC's historical importance in music (like the 1970s-80s Top 40 era) or its later shift to talk radio with figures like Rush Limbaugh? Because those two periods had very different reasons for staying relevant on AM.

Keeping WABC relevant came down to its massive signal reach at night-something FM stations couldn't match back then-which let it dominate the Northeast as a 50,000-watt clear-channel powerhouse. Compared to a local FM outlet that fades after sunset, WABC's signal traveled hundreds of miles, making it a go-to for Top 40 hits and later talk shows when other AM stations were losing steam.

You know, isn't it interesting how a station can survive just by being the voice of a community when everything else is changing? For WABC, I think it was less about the signal and more about becoming the hub for New York's conservative talk lineup-folks like Rush Limbaugh and Sean Hannity gave it a loyal, passionate audience that FM stations couldn't replicate. Does that ring true to you, or am I overthinking it?
