What happened first the release of the anthology of American folk music the first Newport folk festival ww2 or the first broadcast of the grand ole opry?

The first broadcast of the Grand Ole Opry occurred in 1925, making it the earliest of the three events. The anthology of American Folk Music was released in 1952, and the first Newport Folk Festival took place in 1959. World War II spanned from 1939 to 1945, so it occurred between the first broadcast of the Grand Ole Opry and the release of the anthology.
