For over five decades, Michael D. Eisner has been a leader in the American entertainment industry. He began his career at ABC, where he helped take the network from number three to number one in prime-time, daytime, and children's television. In 1976 he became president of Paramount Pictures, turning out hit films such as Raiders of the Lost Ark and Saturday Night Fever. In 1984 Eisner was appointed chairman and CEO of The Walt Disney Company and, in the ensuing twenty-one years, transformed it from a film and theme park company with $1.8 billion in enterprise value into a global media empire valued at $80 billion. In 2005 Eisner founded The Tornante Company, a privately held corporation that invests in, acquires, and operates media and entertainment companies including The Topps Company; has produced television shows including the acclaimed animated series BoJack Horseman through its independent studio; and has owned the Portsmouth Football Club since 2017.
