Digital distribution (also called content delivery, online distribution, or electronic software distribution (ESD), among others) describes the delivery of media content such as audio, video, software and video games, without the use of physical media usually over online delivery mediums, such as the Internet. Digital distribution bypasses conventional physical distribution methods, such as paper or DVDs. The term online distribution is typically applied to freestanding products; downloadable add-ons for other products are more commonly known as downloadable content. An online service for distribution of application software is usually called an "application store" or "app store". With the advancement of network bandwidth capabilities, digital distribution become prominent in the 2000s.
Content distributed online may be streamed or downloaded. Streaming involves downloading and using content "on-demand" as it is needed. Meanwhile, fully downloading the content to a hard drive or other form of storage media allows for quick access in the future.
