Rappers often sing about money, and money sticks to hip-hop. But it was not always so. Three Kings is the story of the rise of the genre's richest exponents - Dr. Dre, Diddy and Jay-Z - to global fame and status as business geniuses. With a track record of S. Carter sneakers, Beats headphones, Ciroc vodka, Revolt TV, these three seem like they can turn any idea into gold. However, in their lives there were failures, and wars, and inevitable losses - their intuition and methods were literally forged on the streets at a time when rap was a marginal and dangerous phenomenon, and not the universal language of the planet. American journalist and Forbes author Zach O'Malley Greenberg reveals through the biographies of three kings the cultural and economic history of hip-hop: from painted subway cars and the first attempts to rap to the beat to platinum discs and multimillion-dollar advertising contracts.
