""Consumers weren't waking up in the morning going, 'I really need to have Nick Cave reading his book along with a soundtrack.' We were solving a problem that didn't exist," Mr. Collingridge says.
Susan Moldow, publisher of Scribner, which recently released an enhanced version of Stephen King's novel "11/22/63," said her company is proceeding with caution.
"We haven't proven there's a big enough market for the enhanced e-book to justify the effort, time and money," she says.
The enhanced version of Mr. King's novel, which includes a 13-minute film written and narrated by the author, has sold 45,000 copies at $16.99. The hardcover version, by contrast, sold close to a million copies at $35.00, and the unadorned digital version has sold nearly 300,000 copies at $14.99. Most enhanced e-books sell in the low thousands, according to publishers."
