Sony Music Publishing LLC (formerly Sony/ATV Music Publishing) is an American music publisher. Responsible for publishing the largest quantity of music, with over five million songs owned or administered as of end March 2021, it is part of Sony Music Group, which is itself owned by Japanese conglomerate Sony Group Corporation. The company was formed as Sony/ATV in 1995 by the merger of the original incarnation of Sony Music Publishing and ATV Music, which was owned by late entertainer Michael Jackson. Jackson had purchased ATV Music, which included the Lennon–McCartney song catalog, in 1985.
In 2012, an investor consortium led by Sony/ATV Music Publishing acquired EMI Music Publishing to become the largest music publishing administrator in the world, with a library of over three million songs.
In April 2019, Jon Platt became CEO/Chairman of Sony/ATV Music Publishing after the contract of longtime CEO/Chairman Martin Bandier expired. In August 2019, management of Sony/ATV Music Publishing and Sony Music Entertainment were merged under the newly formed Sony Music Group.
