Yes, Stephen King is right: His fans like long books. People like suspense, and lengthy books prolong it. But the busy and/or lazy among us might also become fans if half-as-long versions of his golden oldies were available. (Call the line “All the horror in half the time.”) Reader’s Digest once published a series of “condensed books,” but there were mostly literary classics. Do the same for popular best-sellers, like King’s tales, and the format might be more successful, breathing new life into old titles. Heck, could even do the opposite: Publish extra-long versions. (Like a movie with added scenese.) A publicity-generating challenge.
