Social media are a central part of the experience of using the internet, and indeed much current research tends to be about social media rather than ‘the internet’ as such.

Recently there was a discussion on the AoIR email list regarding definitions of social media, and I’m just summarising what was said there for my own benefit, my students, and anyone else who is interested.

The definition I have been mostly using is:

Social Media is a group of Internet-based applications that build on the ideological and technological foundations of Web 2.0, and that allow the creation and exchange of User Generated Content. (Kaplan & Haenlein 2010: 61)

I tend to leave out the reference to ‘Web 2.0’ when I share this one with students, although it is historically accurate, because it requires extra explanation that is not usually important in the context of the class. Nonetheless, it is an important reminder of how social media have mostly developed as commercial endeavours designed to extract value from various forms of immaterial labour (digital, affective, emotional, etc.).

I like the Kaplan and Haenlein paper also because of the way they map out different dimensions of ‘Self presentation/disclosure’ and ‘Social presence/Media richness.’ This helps to think about the different interactive environments online.

In ‘Social Media: Defining, Developing, and Divining,’ Carr and Hayes (2015) provide an excellent discussion and breakdown of social media.

They have two definitions (pp 49–50)– a “precise [but] admittedly complex and technical” one:

Internet-based, disentrained, and persistent channels of masspersonal communication facilitating perceptions of interactions among users, deriving value primarily from user-generated content.

and a “a rephrased, slightly more verbose, but potentially more accessible explication”

Social media are Internet-based channels that allow users to opportunistically interact and selectively self-present, either in real-time or asynchronously, with both broad and narrow audiences who derive value from user-generated content and the perception of interaction with others.

They explain the components of these definitions in detail (e.g. ‘disentrained’ means communication where the two parties can choose to participate at will, and do not need to be committed at the same time as would happen in face-to-face communication).

Interestingly, there is a difference that arises with Kaplan and Haenlein’s model. Carr and Hayes also lay out some examples in a table, and for example, Wikipedia does not make it into their definition of social media, and nor does Tumblr.

Neither of the above definitions are included in a “non-exhaustive” overview of definitions of social media in Fuchs (2017: 37–39; prepublication chapter available here.

McCay-Peet and Quan-Haase (2017: 17) also overview the academic discussions and offer this definition:

Social media are web-based services that allow individuals, communities, and organizations to collaborate, connect, interact, and build community by enabling them to create, co-create, modifies, share, and engage with user-generated content that is easily accessible.

Kietzmann et al. (2011: 243) also offer a typology that emphasises the different functionality of social media. They put identity at the centre, which is an important reminder of how social media are become increasingly important for users’ conception of their self and of others.

Jean Burgess, an editor of the forthcoming ‘SAGE Handbook of Social Media’ (Burgess & Poell 2017) provided a definition that will be included there:

By social media technologies, we mean those digital platforms, services and apps built around the convergence of content sharing, public communication, and interpersonal connection.

Margetts et al. (2015: 5) offer:

Internet-based platform that allows the creation and exchange of user-generated content, usually using either mobile or web-based technologies

Social Media as Text, not Platform

All of the above have a focus on the functionality of the software. One important departure from this focus comes from Miller et al., a team that carried out an exemplary ethnographic comparative project on the use of social media (Why We Post). They state:

Social media should not be seen primarily as the platforms upon which people post, but rather as the contents that are posted on these platforms. (Miller et al. 2016: 61)

This comes from an approach that emphasises sociality as text and is based on the premise that all interactions are mediated, and therefore focusing on the medium (that mediates interaction) takes second place to the content (symbolic, practical) of that interaction.

In anthropology, there is no such thing as pure human immediacy; interacting face-to-face is just as culturally inflected as digitally mediated communication (Miller and Horst 2012: 12)

Note on Social Network Sites

An important distinction needs to be mentioned also – social network sites (SNS) are not the same as social media, but useful to consider in this context also. The most commonly used definition of SNS is by Ellison and boyd (updated from their 2007 paper):

A social network site is a networked communication platform in which participants 1) have uniquely identifiable profiles that consist of user-supplied content, content provided by other users, and/or system level data; 2) can publicly articulate connections that can be viewed and traversed by others; and 3) can consume, produce, and/or interact with streams of user-generated content provided by their connections on the site. (2013: 158; original emphasis)

Social and Mobile Media

Finally, I’d just like to add my own working definition that I offer students:

Social media are computer-mediated communication software that enable users to create, share and view content in publicly networked one-to-one, one-to-many, and/or many-to-many communications.

Also, I have usually found myself referring to ‘social and mobile media’ as a catchall so as to be able to include ‘over-the-top’ instant messaging apps (such as WhatsApp) that are widely used (though not everywhere, for example in the USA about 29% use these, compared to 92.7% in Malaysia).
