WSM AM 650 is a legendary clear-channel radio station based in Nashville, Tennessee, operating since 1925. It is best known as the home of the Grand Ole Opry, the longest-running live radio broadcast in the world. The station specializes in country music and has played a pivotal role in popularizing the genre across the United States. Its powerful signal allows it to reach much of North America at night. WSM's call letters stand for "We Shield Millions," a nod to its founding by the National Life and Accident Insurance Company.
