We Save Millions. It's the tagline for the insurance company that originally sponsored the Opry Show
WSM is the callsign letters for a clear channel AM radio station located here in Nashville, Tennessee. It broadcasts the Opry ahows live nationwide. The call letters were specifically chosen back in 1925 to stand for "We Shield Millions". Which was the slogan back then for the stations owners, the National Life and Accident Insurance Company. WSM is broadcast on a frequency of 650 AM. It's also available online at wsm.com, and is broadcast on satellite radio as well.
They are the call letters to the radio station that broadcast live during the show.
