The planned merger of Random House owned by Bertelsmann, and Penguin owned by Pearson, creates the largest consumer book publisher in the world with a 25% market share. Bertelsmann will control 53% of the new entity, and Pearson 47%. The merger will help the new entity better handle the challenges presented by the shift to electronic books and internet retailing, and respond to the power of large companes such as Apple, Amazon and Google in this field. This creates pressure for mergers among the other large publishers, Hatchette owned by Lagardere in France, HarperCollins a part of News Corporation, Macmillan part of Georg von Holtzbrinck in Germany, and Simon & Schuster a part of CBS.
