Success in marketing directly to avid readers has lead to an extensive growth of programs, as well as the identification of smaller segments within this broad market. In ride-alongs and package insert programs, mail-order book buyers disclose their preferences for sub-categories of books with topics such as mystery, military history and science fiction, to name a few. Consumers, interested in previewing the latest books, look forward to receiving their literary review in order to decide which books to purchase. By advertising in many programs that Echo Media offers, reaching this book-loving market has become easier than ever.
