To produce the SKU, warehouse workers pick the component pieces and bring them to the production line, where the digital content is imprinted on the media and the package is assembled. The SKU then travels to the finished-goods warehouse, where it is picked as part of an order for shipment to a distributor. The distributor receives titles from many producers and later picks the SKU as part of an order for shipment to a retailer. Finally, the end user goes to the retailer—in person, by phone, or over the Internet—and selects the CD.
