Columbia Records, founded in 1887, is an American record label owned by Sony Music Entertainment. The oldest surviving brand in the recorded sound business, Columbia had accrued an impressive catalog of blues and jazz music by the mid 1920s. During this time, prominent jazz artists such as Louis Armstrong, Clarence Williams, and Bessie Smith were on Columbia’s roster. The label’s jazz catalog only grew in significance through the 1950s and beyond, as Columbia released several Miles Davis albums including the seminal Kind of Blue. Other essential artists who had their albums released on Columbia include Duke Ellington, Charles Mingus, Thelonious Monk, Billie Holiday, and Tony Bennett. In the 1980s, Columbia was acquired by Sony, who maintains the rights to Columbia and its copyrights today. As of 2013, 90 artists were signed to Columbia Records.
