This chapter demonstrates how different global value surveys have confirmed what any observant and educated global traveller knows—that even in similarly developed countries, people have different values and tastes and, consequently, they read different books. Further, the chapter explains how the global spread of printing technology and market forces have produced similar results in all book markets worldwide. First, the number of published titles is rapidly increasing. Second, the number of bestsellers and print runs per title are decreasing, although a very few blockbuster titles stand outas exceptions. Third, due to the first two trends, publishers’ average income per title has decreased so that the entire book industry has become increasingly dependent on bestsellers. Yet, due to value differences among countries and cultures, the traditional publishing business model has come under a number of pressures and a variety of new book ecosystems has emerged.
