How do you sell mainstream Digital goods online such as movies music and books?
Most important about such content share is managing its rights, called Digital Content Copy Rights. Solutions (incl. software+hardware+legal) built to protect and control these rights are often called Digital Rights Management (DRM) systems.Unless you are planning to build an online bookstore or an online library, you don't have to buy and build these systems if you want to share your content online. You can simply choose a company offering these services online.For books, Lulu and Blurb are the first two when you search "publish book" on Google but I'd definitely suggest to consider publishing your book for portable devices through iBooks and Google Play.For videos, it gets more complicated depending on live stream broadcasting or video clips, etc. liveStream, ustream, or vmix will probably satisfy any needs. On the other hand, well known video content publishers such as Youtube and Vimeo also offer earnings through the model called "monetization". Simply put, they ask your permission to display video ads at the beginning and end of your content and offering you a percentage of what they earn per view.
