I want to know the answer to the following question:
Who contributed to the idea that the mandolin was a fad?
All the background I'm provided with is that "This "mandolin craze" was fading by the 1930s, but just as this practice was falling into disuse, the mandolin found a new niche in American country, old-time music, bluegrass and folk music.". Is that enough to answer the question?
Answer: no
