Along with business partner, Jack Canfield , Hansen is best known for creating what Time magazine called “the publishing phenomenon of the decade”. Chicken Soup for the Soul books are one of the most successful publishing franchises in the world today, with more than 500 million books sold internationally and more than 100 licensed products.
