Sony renamed the record company Sony Music Entertainment (SME) on January 1, 1991, fulfilling the terms set under the 1988 buyout, which granted only a transitional license to the CBS trademark. The CBS Associated label was renamed Epic Associated. Also on January 1, 1991, to replace the CBS label, Sony reintroduced the Columbia label worldwide, which it previously held in the United States and Canada only, after it acquired the international rights to the trademark from EMI in 1990. Japan is the only country where Sony does not have rights to the Columbia name as it is controlled by Nippon Columbia, an unrelated company. Thus, until this day, Sony Music Entertainment Japan does not use the Columbia trademark for Columbia label recordings from outside Japan which are issued in Japan. The Columbia Records trademark's rightsholder in Spain was Bertelsmann Music Group, Germany, which Sony Music subsequently subsumed via a 2004 merger, followed by a 2008 buyout.
