Grand Ole Opry House

The Grand Ole Opry is a regular live country-music radio broadcast originating from Nashville, Tennessee, on WSM, held between two and five nights per week, depending on the time of year. It was founded on November 28, 1925, by George D. Hay as the WSM Barn Dance, taking its current name in 1927. Currently owned and operated by Opry Entertainment, it is the longest-running radio broadcast in U.S. 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.
