Seth Godin on Audio Books

Self-help author Seth Godin has a short entry on the topic of audio books:

The reason for the market failure is historic. Audio books traditionally generate very little revenue to the author. She gets a royalty on a royalty on a small sales base. Not worth the time to promote. Add to that the huge hassle of keeping a large number of titles in stock at a retailer and throw in the high price required by producing many CDs or cassette tapes per title, and you see the problem.
