The Grand Ole Opry is a weekly country music stage concert in Nashville, Tennessee that has presented the biggest stars of that genre. Founded on November 28, 1925 by George D. Hay as a one-hour radio "barn dance" on WSM, it is also among the longest-running broadcasts in history. Dedicated to honoring country music and its history, the Opry showcases a mix of legends and contemporary chart-toppers performing country, bluegrass, folk, gospel, and comedic performances and skits. Considered an American icon, it attracts hundreds of thousands of visitors from around the world and millions of radio and Internet listeners. The Opry is "the show that made country music famous" and has been called the "home of American music" and "country’s most famous stage." The Grand Ole Opry is owned and operated by Ryman Hospitality Properties, Inc.
In the 1930s, the show began hiring professionals and expanded to four hours; and WSM, broadcasting by then with 50,000 watts, 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". The Grand Ole Opry holds such significance in Nashville that its name is included on the city/county line signs on all major roadways. The signs read "Music City | Metropolitan Nashville Davidson County | Home of the Grand Ole Opry".
