Digital Products Digital products (information products): software, video, music, e- book, articles, reports, news … They dont have physical appearance They are easy to be mass-customized and personalized They can be delivered at the time of purchase Fixed cost is high while marginal cost is close to zero The distribution of information products is expected to change dramatically in future They have global reach They foster disintermediation Information product medium is less important Unbundling: only pay for the part you want Micro-payments
