Examples of digital media include software, digital images, digital video, video games, web pages and websites, social media, digital data and databases, digital audio such as MP3, and electronic books.
Computer software includes computer programs, libraries and related non-executable data, such as online documentation or digital media.

Social media

Examples of digital media include software, digital images, digital video, video games, web pages and websites, social media, digital data and databases, digital audio such as MP3, and electronic books. Though the essay predated digital computers by several years, "As We May Think," anticipated the potential social and intellectual benefits of digital media and provided the conceptual framework for digital scholarship, the World Wide Web, wikis and even social media.
An important feature of social media is digital media data compression, due to the impractically high memory and bandwidth requirements of uncompressed media.

Content creation

Digital media has also posed new challenges to copyright and intellectual property laws, fostering an open content movement in which content creators voluntarily give up some or all of their legal rights to their work.
Typical forms of content creation include maintaining and updating web sites, blogging, article writing, photography, videography, online commentary, the maintenance of social media accounts, and editing and distribution of digital media.

Digital dark age

Dark Agesdigital "dark age
However, challenges to a digital transition remain, including outdated copyright laws, censorship, the digital divide, and the spectre of a digital dark age, in which older media becomes inaccessible to new or upgraded information systems.
One concern leading to the use of the term is that documents are stored on physical media which require special hardware in order to be read and that this hardware will not be available in a few decades from the time the document was created.

Digital distribution

Practical digital multimedia distribution and streaming was made possible by advances in data compression, due to the impractically high memory, storage and bandwidth requirements of uncompressed media.
Digital distribution (also referred to as content delivery, online distribution, or electronic software distribution (ESD), among others) is the delivery or distribution of digital media content such as audio, video, e-books, video games, and other software.

Discrete cosine transform

DCTiDCTinverse discrete cosine transform
The most important compression technique is the discrete cosine transform (DCT), a lossy compression algorithm that was first proposed as an image compression technique by Nasir Ahmed at the University of Texas in 1972.
It is used in most digital media, including digital images (such as JPEG and HEIF, where small high-frequency components can be discarded), digital video (such as MPEG, H.26x and Vorbis), digital audio (such as Dolby Digital, MP3 and AAC), digital television (such as SDTV, HDTV and VOD), digital radio (such as AAC+ and DAB+), and speech coding (such as AAC-LD, Siren and Opus).

Paperless society

The ubiquity of digital media and its effects on society suggest that we are at the start of a new era in industrial history, called the Information Age, perhaps leading to a paperless society in which all media are produced and consumed on computers.

Digital scholarship

Though the essay predated digital computers by several years, "As We May Think," anticipated the potential social and intellectual benefits of digital media and provided the conceptual framework for digital scholarship, the World Wide Web, wikis and even social media. In academia, digital media has led to a new form of scholarship, called digital scholarship, and new fields of study, such as digital humanities and digital history.
Digital scholarship can encompass both scholarly communication using digital media and research on digital media.

The most important compression technique is the discrete cosine transform (DCT), a lossy compression algorithm that was first proposed as an image compression technique by Nasir Ahmed at the University of Texas in 1972.
The DCT is the most widely used data compression transformation, the basis for most digital media standards (image, video and audio) and commonly used in digital signal processing.

Computer

The first truly digital media came into existence with the rise of digital computers.
Computer software includes computer programs, libraries and related non-executable data, such as online documentation or digital media.

Information Age

The ubiquity of digital media and its effects on society suggest that we are at the start of a new era in industrial history, called the Information Age, perhaps leading to a paperless society in which all media are produced and consumed on computers.
Discrete cosine transform (DCT) coding, a data compression technique first proposed in 1972, enabled practical digital media transmission, with image compression formats such as JPEG (1992), video coding formats such as H.26x (1988 onwards) and MPEG (1993 onwards), audio coding standards such as Dolby Digital (1991) and MP3 (1994), and digital TV standards such as video-on-demand (VOD) and high-definition television (HDTV).

Mass media

Compared with print media, the mass media, and other analog technologies, digital media are easy to copy, store, share and modify.
Digital media comprises both Internet and mobile mass communication.

Digital history

In academia, digital media has led to a new form of scholarship, called digital scholarship, and new fields of study, such as digital humanities and digital history.
Digital history is the use of digital media to further historical analysis, presentation, and research.

Digital journalism

But the rise of digital journalism has also created thousands of new jobs and specializations.
What constitutes digital journalism is debated by scholars; however, the primary product of journalism, which is news and features on current affairs, is presented solely or in combination as text, audio, video, or some interactive forms like newsgames, and disseminated through digital media technology.

Digital Revolution

This led to the development of the personal computer (PC) in the 1970s, and the beginning of the microcomputer revolution and the Digital Revolution.
DCT compression later became fundamental to the Digital Revolution, as the basis for most digital media compression standards from the late 1980s onwards, including digital image formats such as JPEG (1992), video coding formats such as H.26x (1988 onwards) and MPEG (1993 onwards), audio compression standards such as Dolby Digital (1991) and MP3 (1994), and digital television standards such as video-on-demand (VOD) and high-definition television (HDTV).

Multimedia

Practical digital multimedia distribution and streaming was made possible by advances in data compression, due to the impractically high memory, storage and bandwidth requirements of uncompressed media.
Technology has impacted multimedia as it is largely associated with the use of computers or other electronic devices and digital media due to its capabilities concerning research, communication, problem-solving through simulations and feedback opportunities.

Video coding format

The DCT algorithm was the basis for the first practical video coding format, H.261, in 1988.
Its motion-compensated DCT algorithm was able to achieve a compression ratio of up to 100:1, enabling the development of digital media technologies such as video-on-demand (VOD) and high-definition television (HDTV).

Electronic media
