Article: German record company Odeon is often said to have pioneered the album in 1909 when it released the Nutcracker Suite by Tchaikovsky on 4 double-sided discs in a specially designed package. (It is not indicated what size the records are.) However, Deutsche Grammophon had produced an album for its complete recording of the opera Carmen in the previous year. 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).

Now answer this question: When were albums said to be pioneered?
1909
