I would be extremely curious if this holds for content as well as app. We've trained users that content is free, while apps can occasionally cost money. This has led to all kinds of price distortions in music and, most especially, ebooks.

As a content producer who works closely with engineers, I can vouch that good content requires no less training and effort than good apps. A novel-length ebook probably takes more time and effort to produce (for any level of quality) than an app. I'd imagine an album of music requires even more. Yet we we never hear stories about perfect price elasticity in content.

I'm genuinely curious if price elasticity holds true in content and, if so, why we haven't heard as much about it.
