The Grand Ole Opry is a weekly American country music stage concert in Nashville, Tennessee, founded on November 28, 1925, by George D. Hay as a one-hour radio "barn dance" on WSM. Currently owned and operated by Opry Entertainment, it is the longest-running radio broadcast in US history. Dedicated to honoring country music and its history, the Opry showcases a mix of famous singers and contemporary chart-toppers performing country, bluegrass, Americana, folk, and gospel music as well as comedic performances and skits. It attracts hundreds of thousands of visitors from around the world and millions of radio and internet listeners.
In the 1930s, the show began hiring professionals and expanded to four hours. Broadcasting by then at 50,000 watts, WSM made the program a Saturday night musical tradition in nearly 30 states. In 1939, it debuted nationally on NBC Radio. The Opry moved to a permanent home, the Ryman Auditorium, in 1943. As it developed in importance, so did the city of Nashville, which became America's "country music capital."
