It's officially cited in the Guinness Book of World Records as the planet's oldest continuous radio show - and it's still on the air. Nov. 28th marks 97 years and counting for what started as the "Barn Dance" in 1925. It would eventually change its name to the moniker it boasts all these years later - The Grand Ole Opry. 

It began as an imitation of a similar show on WLS in Chicago, a program which is long gone. But the Opry lives on, a staple of the legendary 50,000-watt Nashville country powerhouse WSM. (Which may also hold the record for having the same format in radio history.)  

Among those who got their start on the Opry - Gene Autry, Dolly Parton and Johnny Cash. Just to name a few. 

It is a remarkable legacy, likely never to be broken. Except by maybe those tiresome Spence Diamond ads that appear on local radio. It seems like they've been running forever!

On this day in history, Nov. 28, 1925, Grand Ole Opry debuts on WSM radio in Nashville
