Tommy Mottola
During his tenure, he transformed Sony into one of the most successful global music companies, expanding its businesses into over 60 countries, while creating one of the strongest management teams in the industry.  He revitalized Sony Music's publishing division by making such acquisitions as the Beatles catalogue and enabled Sony to become the first major music company to make available commercial digital downloads. He is widely well known for signing, developing, and nurturing the careers of Mariah Carey, Celine Dion, Destiny's Child, Jennifer Lopez, Shakira, Gloria Estefan, the Dixie Chicks, Marc Anthony, Barbra Streisand, Bruce Springsteen, Billy Joel, among others. He also worked with Michael Jackson from the time he began recording his "Dangerous" (1991) album. Jackson would later state that his relationship with Mottola dissolved based on corruption in his working practices, publicly referring to him as a "racist" and "devil". "The recording companies really, really do conspire against the artists." Jackson said.(source: Vh1).
