Atlantic Recording Corporation (simply known as Atlantic Records) is an American major record label founded in October 1947 by Ahmet Ertegün and Herb Abramson. Over its first 20 years of operation, Atlantic Records earned a reputation as one of the most important American recording labels, specializing in jazz, R&B and soul recordings by African-American musicians including Aretha Franklin, Ray Charles, Wilson Pickett, Sam and Dave, Ruth Brown and Otis Redding, a position greatly enhanced by its distribution deal with Stax Records. In 1967, Atlantic Records became a wholly owned subsidiary of Warner Bros.-Seven Arts, now the Warner Music Group, and expanded into rock and pop music with releases by bands such as Led Zeppelin and Yes. 

In 2004, Atlantic Records and its sister label Elektra Records merged into Atlantic Records Group. Craig Kallman is currently the chairman of Atlantic Records. Ahmet Ertegün served as founding chairman until his death on December 14, 2006, at age 83.
