The Last Mogul: The Life and Times of Lew Wasserman (2005):

Barry Avrich’s deeply researched look at one of Hollywood’s most influential leaders of the 20th century neither canonizes nor demonizes its complex subject. Wasserman, whose MCA Inc. was a forerunner of the modern media conglomerate, is brought to life in a warts-and-all portrait that details how his business acumen and vision changed the industry.
