According to the Wall Street Journal (Feb 6, page B2), when Audible (Amazon.com’s audiobook subscription service) “owns the audiobook rights, print publishers no longer get a cut. Typically, this means more money is passed on to the author.” And revenue from audiobook sales is rising, “In the first eight months of 2017, publishers’ revenue from audiobooks grew 20% for the same period a year earlier, while print books only rose 1.5% and e-books slipped 5.4%.”
