I want to know the answer to the following question:
When were albums said to be pioneered?
All the background I'm provided with is that "The practice of issuing albums does not seem to have been widely taken up by other record companies for many years; however, HMV provided an album, with a pictorial cover, for the 1917 recording of The Mikado (Gilbert & Sullivan).". Is that enough to answer the question?
Answer: no
