Over the years, Disney books have evolved to reflect changing reader interests and advances in technology. The 1960s and 1970s saw the introduction of Disney's first paperback books, making Disney stories more accessible to a wider audience. The 1980s and 1990s witnessed the rise of Disney's publishing partnerships with major publishers like Random House and Simon & Schuster. These partnerships led to the creation of new book series, such as the "Disney's Wonderful World of Reading" and "Disney's Little Muppet Books."
