E-books in the context of "ITunes"

Digital distribution, also referred to as content delivery, online distribution, or electronic software distribution, among others, is the delivery or distribution of information or materials through digital platforms. The distribution of digital media content may be of digitized versions of analog materials, as well as other materials offered in a purely digital format, such as audio, video, e-books, video games, and other software.

The term is generally used to describe distribution over an online delivery medium, such as the Internet, thus bypassing physical distribution methods, such as paper, optical discs, and VHS videocassettes. The term online distribution is typically applied to freestanding products, with downloadable add-ons for other products are more commonly described as downloadable content. Content distributed online may be streamed or downloaded, and often consists of books, films and television programs, music, software, and video games. Streaming involves downloading and using content at a user's request, or "on-demand", rather than allowing a user to store it permanently. In contrast, fully downloading content to a hard drive or other forms of storage media may allow offline access in the future.

The term born-digital refers to materials that originate in a digital form. This is in contrast to digital reformatting, through which analog materials become digital, as in the case of files created by scanning physical paper records. It is most often used in relation to digital libraries and the issues that go along with said organizations, such as digital preservation and intellectual property. However, as technologies have advanced and spread, the concept of being born-digital has also been discussed in relation to personal consumer-based sectors, with the rise of e-books and evolving digital music. Other terms that might be encountered as synonymous include "natively digital", "digital-first", and "digital-exclusive".
