An apt analogy
For readers, e-books have meant a transformation not just of the reading experience, but of the book-buying tradition of strolling aisles, perusing covers and being able to hold books in their hands. Many publishers have been astounded by the pace of the e-book popularity and the threat to print book sales that it represents. If the number of brick-and-mortar stores drops, publishers fear that sales will go along with it. Some worry that large bookstores will go the way of the record stores that shut down when the music business went digital.
