Digital music was doable, but wasn&#x27;t easy until Apple did the business work necessary to make the iTunes Music Store possible. eBook access to the latest publications on day-of publication across fiction and nonfiction was functionally a non-starter until Amazon did the business work necessary to make the Kindle Store possible.
