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.

Specialist networks known as content delivery networks help distribute content over the Internet by ensuring both high availability and high performance. Alternative technologies for content delivery include peer-to-peer file sharing technologies. Alternatively, content delivery platforms create and syndicate content remotely, acting like hosted content management systems.

Unrelated to the above, the term "digital distribution" is also used in film distribution to describe the distribution of content through physical digital media, in opposition to distribution by analog media such as photographic film and magnetic tape (see: digital cinema).

Impact on traditional retail The rise of online distribution has provided controversy for the traditional business models and resulted in challenges as well as new opportunities for traditional retailers and publishers. Online distribution affects all of the traditional media markets, including music, press, and broadcasting. In Britain, the iPlayer, a software application for streaming television and radio, accounts for 5% of all bandwidth used in the United Kingdom.

Music The move towards online distribution led to a dip in sales in the 2000s; CD sales were nearly cut in half around this time. One such example of online distribution taking its toll on a retailer is the Canadian music chain Sam the Record Man; the company blamed online distribution for having to close a number of its traditional retail venues in 2007–08. One main reason that sales took such a big hit was that unlicensed downloads of music were very accessible. With copyright infringement affecting sales, the music industry realized it needed to change its business model to keep up with the rapidly changing technology. The step that was taken to move the music industry into the online space has been successful for several reasons. The development of lossy audio compression file formats such as MP3 could take 30 MB for a typical 3-minute song and bring it down to 3 MB without any serious loss of quality. Lossless FLAC files can be up to six times larger than an MP3 while, in comparison, the same song might require 30–40 megabytes of storage on a CD. The smaller file size yields much greater Internet transfer speeds.

The transition into the online space has boosted sales, and profit for some artists. It has also allowed for potentially lower expenses such as lower coordination costs, lower distribution costs, as well as the possibility for redistributed total profits. These lower costs have aided new artists in breaking onto the scene and gaining recognition. In the past, some emerging artists have struggled to find a way to market themselves and compete in the various distribution channels. The Internet may give artists more control over their music in terms of ownership, rights, creative process, pricing, and more. In addition to providing global users with easier access to content, online stores allow users to choose the songs they wish instead of having to purchase an entire album from which there may only be one or two titles that the buyer enjoys.

The number of downloaded single tracks rose from 160 million in 2004 to 795 million in 2006, which accounted for a revenue boost from US$397 million to US$2 billion. Downloading peaked in the US in 2012, after which it started falling due to the rise of music streaming services. In 2017, physical formats overtook downloading again for the first time in six years, but despite the vinyl revival and CDs holding its own, the physical formats account for only 11% revenue as of 2023, while streaming services are dominant with 84% of the US industry.

A music download is the digital transfer of music via the internet into a device capable of decoding and playing it, such as a personal computer, portable media player, MP3 player, or smartphone. This term encompasses both legal downloads and downloads of copyrighted material without permission or legal payment. Music downloads are typically encoded with the MP3 audio coding format. or using the modified discrete cosine transform (MDCT) audio data compression, particularly the Advanced Audio Coding (AAC) format used by iTunes.

Since the advent of streaming, downloads as a mode of music distribution has seen a steady decline from its peak in the early 2010s. According to a Nielsen report, downloadable music accounted for 55.9 percent of all music sales in the US in 2012."All music sales" refers to albums plus track equivalent albums. A track equivalent album equates to 10 tracks. By the beginning of 2011, Apple's iTunes Store alone made 1.1 billion of revenue in the first quarter of its fiscal year., FierceMobileContent 19 January 2011 According to the RIAA, music downloads peaked at 43% of industry revenue in the US in 2012, and has since fallen to 3% in 2022.

Paid downloads are sometimes encoded with digital rights management that restricts copying the music or playing purchased songs on certain digital audio players. They are almost always compressed using a lossy codec (usually MPEG-1 Layer 3, Windows Media, or AAC), which reduces file size and bandwidth requirements. These music resources have been created as a response to expanding technology and needs of customers who wanted and/or needed easy, quick access to music. Their business models respond to the "download revolution" by making legal services attractive for users.

Even legal music downloads have faced a number of challenges from artists, record labels and the Recording Industry Association of America (RIAA). In July 2007, the Universal Music Group decided not to renew their long-term contracts with iTunes. This decision was primarily based on the issue of pricing of songs, as Universal wanted to be able to charge more or less depending on the artist, a shift away from iTunes' standard—at the time—99 cents per song pricing. Many industry leaders feel that this is only the first of many show-downs between Apple Inc. and the various record labels.

According to research by the website TorrentFreak, 38 percent of Swedish artists support file share downloading and claim that it helps artists in early career stages. Artists, including Swedish rock group Lamont, have profited from file sharing."Swedish artists want to legalize filesharing" 17 October 2011

RIAA against illegal downloading In the early 2000s, the peer-to-peer file sharing company Napster was sued due to mass infringement of music ownership copyrights by a collection of recording companies (A&M Records, Inc. v. Napster, Inc.)—a lawsuit which issued a preliminary injunction for the service and was concluded by the closure of the Napster free music sharing between its users.

The RIAA oversees about 85 percent of published music production, distribution and manufacturing in the United States. Their stated goal is to support artists' creativity and help them not be cheated out of money by illegal downloading. The RIAA launched its first lawsuits of individuals (P2P file swappers) on 8 September 2003, against users who illegally downloaded music files from the Kazaa FastTrack network.

RIAA claimed it filed 750 suits in February 2006 against individuals downloading music files without paying for them in hopes of putting an end to Internet music piracy. With this campaign the RIAA hoped to force people to respect the copyrights of music labels and minimize the number of illegal downloads.Jason Krause. "Breaking up downloading".

Sales records The Official Charts Company began to incorporate downloads in the UK Singles Chart on 17 April 2005, at which time Radio 1 stopped broadcasting the separate download chart, although the chart is still compiled. Initially this was on condition that the song must have a physical media release at the same time; this rule was fully lifted on 1 January 2007, meaning all download sales are now eligible in the chart.
