The Grand Ole Opry began in 1925 as a weekly country music concert aired on station WSM in Nashville. It is now the country’s longest-running broadcast show. The variety program was performed at the Ryman Auditorium from 1943 until 1974. Then, it moved to the Grand Ole Opry House (although the show returns to the Ryman during the winter). Membership as a cast member in the Grand Ole Opry is a coveted honor. Performers are selectively chosen and formally inducted. They are then obligated to perform a minimum number of times each year during the balance of their career. Avid country music fans dream of making a pilgrimage to the Grand Ole Opry House to hear a live show in the 4,400 seat theater. Tours are also available including a peek backstage.
