Sourcebooks-backed Penguin Random House, a company that prints and publishes books, completed the acquisition of Callisto Media, a California-based digital media and publishing company that offers non-fiction books for global distributions. Financial terms were not disclosed. "We are excited to continue to build the future of the Callisto publishing program with our partners at Penguin Random House. For four years, Sourcebooks and Penguin Random House have mutually enjoyed an unconventional, highly collaborative partnership, and this deal is another manifestation of our work together. This acquisition brings together two of the most data-driven publishers in the industry to create a consumer-led organization that brings readers books that will change their lives in so many ways. This partnership also allows for an even greater level of innovation that will make an impactful difference for authors. We see data as an enormous creative power," Dominique Raccah, Sourcebooks Publisher and CEO.
