Started in 1918 by Otto K. E. Heinemann.
Beside a regular melting-pot novelty catalog, OkeH focused as well on the immigrant community by issuing records in various languages, then opened its door to the African-American's music and early jazz.
Columbia took Okeh over in November 11, 1926, and discontinued the label operations in 1935.
Eventually they revived it in 1940 until 1946 (having lost Vocalion).
Epic Records took OkeH over in 1965, and still controls it nowadays, under Sony BMG rule.
