Arianna Huffington helped to disrupt and reshape the newspaper business as we once knew it when she co-founded The Huffington Post. In its first week online in 2005, HuffPost had postings from Julia Louis-Dreyfus, Larry David, Gary Hart, John Cusack, and Walter Cronkite. A little more than 10 years later, the site had become one of the most-visited news sites in the world. At that juncture, Arianna stepped down from the site to devote her time to a new startup of hers called Thrive Global that’s focused on health and wellness information. That same year, she published The Sleep Revolution: Transforming Your Life, One Night At A Time. Her book shows how our cultural dismissal of sleep as time wasted compromises our health and our decision-making and undermines our work and our personal lives.
