The book is the oldest form of mass communication. Early books were printed by hand until the invention of movable type and the printing press.
In early America publishers were also printers. Books became more popular during the 17th and 18th -centuries.
From 1900 to 1945, the book publishing industry became more commercialized. Continuing consolidation has resulted in a modern book industry that is dominated by a few large companies.
The digital revolution has yet to have a drastic effect on the book industry. E-books and printing on demand have yet to become important parts of the industry. Despite the slow progress of digital content, there are signs that it is moving forward.
The book industry consists of publishers, distributors, and retailers. The emergence of online booksellers has changed the way books are sold and distributed.
Despite some ups and downs, book publishing has been profitable during the past few decades.
