Freemium is a business model by which a product or service (typically a digital offering such as software, media, games or web services) is provided free of charge, but a premium is charged for advanced features, functionality, or related products and services. [ 1 ] [ 2 ] The word "freemium" is a portmanteau combining the two aspects of the business model: "free" and "premium". [ edit ] Origin The business model has probably been in use for software since the 1980s, particularly in the form of a free time- or feature-limited (' lite ') version, often given away on a floppy disk or CD-ROM, to promote a paid-for full version.
