Defining social media

[Summary: I’ve been looking for a definition of social media to use in research, but without much luck. So, tentatively, here is an attempt to provide one: Social media is the creation, publishing and/or sharing of content from an author to a crowd, providing a locus for horizontal interaction across the crowd. This blog post unpacks, and seeks to justify, this choice of definition]


Definitions are useful things in research and critical thinking around a subject. When studying the youth work uses of social network sites, I found boyd and Ellison’s clear definition of what constitutes a social network site to be extremely useful in giving focus to the work. Right now I’m working with Kevin Harris on an essay around the potential uses of social media in frontline public services, and one of the first challenges I’ve hit is finding an operational definition of social media.

Search the web and you will find plenty of claims about ‘what social media is’ – but they tend either towards explaining what social media is by examples (e.g. ‘social media is sites like Facebook and YouTube’) or to conflate social media with a whole host of other concepts, often in a normative way (e.g. ‘social media is the open and free sharing of content and conversation between people operating as equals.’). A good definition needs to be general enough to pick out all those things which are, by consensus, examples of social media, and to identify new examples of social media, but to also be tight enough to allow us to ask questions about the empirical and normative properties of social media (rather than assuming them). So far, I’ve not found a definition to fit that bill – so, here is a very tentative attempt to provide one.

What do we want from a definition:

A choice has to be made in advancing a definition of social media.

  • Should the definition only pick out those ‘new’ forms of media that we’ve commonly labeled social media, excluding older media by definition? Or should it allow the use of the term (social media) to refer to older things and historical experiences?
  • Should the definition be tied to the digital? Or can there be non-digital social media?
  • How will the definition set out the relationship and order of sub-terms and related terms. For example, is a social media platform something which hosts social media; or is the platform prior, such that social media is anything hosted on a social media platform?
  • Should a definition try to take in all those things that people commonly call ‘social media’, or should it advance the claim that some of the things commonly called social media are, in fact, not.

My own choices are to: allow the terminology of social media to pick out historical phenomena as well as current ones; to talk first about people’s practice, and not to tie the definition to the digital; and to advance a definition which may exclude some things commonly called social media – but generally only as a result of a rejection of the primacy of platforms in defining what is, or isn’t social media.

Offering a definition

Based on those choices, the definition below is my tentative first attempt at capturing the concept of social media.

Social media is the creation, publishing and/or sharing of content from an author to a crowd, providing a locus for horizontal interaction across the crowd.

Or, for those on Twitter, the 140 character version:

Social media=creation, publishing &/or sharing content from author 2 crowd, providing locus 4 horizontal interaction across the crowd (@timdavies, 2009)

Of course, this is still a little dense – but hopefully with some unpacking I can show why I think this captures the essential concept of social media.

Unpacking the definition

Creating, publishing, sharing content

An interaction can only be a social media interaction when there is some media. Be that a video, a photo or a 140 character tweet. I’ve used the term ‘content’ to avoid importing any connotations from the idea of media that might lead people to exclude content such as simple interpersonal messages from their understanding of social media.

[I’m not entirely sure that these three terms are the best for this part of the definition, but retain them for the time being – open to alternative suggestions. They should be read as ‘Creating [and/or] publishing [and/or] sharing’.]

From an author to a crowd

One key difference between an e-mail and a blog post is that the author of the e-mail chooses, in a deliberate and technically defined way (by e-mail addresses), who to address the e-mail to, whereas, with the blog post, they publish to an unspecified or unknown audience.

It is not necessary that the potential audience of an item of content be ‘everyone’ for it to be social media. Social media can be published or shared within a relatively closed community, but it is always published/shared with the possibility of people within the community / domain where into which it is injected ‘overhearing’ or engaging with it – even if they were not the audience the author had in mind.

If you need an analogy – think of relating an anecdote at a crowded party. You have an idea of who is in the room. An idea of who you want to address the anecdote to. But you do not limit who may listen, and you accept injections from those in the room who overhear and engage.

This author->crowd aspect of social media operates at the level of both technology (e.g. the ease of publishing to a community) and at a level of social norms (knowing that people are not obligated to engage with the content produced, but allowing that they can).

A locus for interaction

Social media involves the possibility of interaction. But that interaction need not be described in terms only of some technical functions (e.g. comment boxes and rating boxes). Rather, in social media, content has the potential of becoming a social object around which interaction can be organized – and this can happen in at least two ways (which are not mutually exclusive):

  • The platform through which the content is published allows for or enables comments and interaction;
  • The content is licensed in ways that allow people to share / remix and engage with and around it in active, creative ways;

The interaction need not take place in a single location, or on only on platforms that call themselves ‘social media platforms’.

Horizontal interaction across the crowd

If the only interaction possible around content is between the author and individual members of the ‘audience’ (vertical interaction), then the potential social interaction around the content is highly constrained. In social media, there must be the possibility of audiences of content interacting with each other around or through the content, with or without reference to the originator of the content.

The requirement that the potential must be for horizontal interaction ‘across the crowd’ distinguishes cases where content is broadcast into multiple small ‘crowds’ where it becomes a social object (e.g. a TV programme watched & discussed in living rooms across the country) within sub-units of the whole crowd, from circumstances which can tie together interaction from right across the crowd who constitute the potential audience of the content (e.g. the use of a hash-tag on Twitter to discuss a broadcast media programme or a weather event).

This does not mean that social media necessarily equalizes people – or that all interaction around social media content is horizontal and peer-to-peer in character. But it does suggest that without the potential for horizontal interaction around content, that content is not social media.

Extensions of the definition

The definition unpacked above is essentially the definition of a process (creating, publishing, sharing content) under certain conditions. But from these we can derive a number of further definitions:

  • Social Media Content – content is social media content iff it is created, published and/or shared from author to crowd in a way that can provide a locus for horizontal interaction across the crow
  • A social media platform/tool – is a platform or tool which, to a significant and noticeable extent, intentionally, or unintentionally, facilitates the creation, publishing or sharing of social media

  • Etc.

Testing the definition

I’ve tried in composing this tentative definition to apply a number of tests to check it’s utility. Example tests check if it rightly rules in, and rules out, certain examples of things that may or may not be generally considered to be social media. Question tests check whether the definition can be used to guide substantive enquiries into social media without including the answers to interesting questions in the definition itself.

For example tests, I believe that:

  • This definition adequately rules in as generally social media: YouTube, Facebook & Twitter. I welcome other suggestions of examples to test.
  • This definition rules out TV, E-mail, Telephone Conversations and Podium Speeches as not being examples of social media. It also rules out use of tools such as YouTube solely as media publishing platforms when all interactive features are turned off. An online video with no interactive features is only made into a social object when shared by someone who adds opportunities for interactivity to it – in which case the ‘social media’ consists of the original non-interactive video, plus the sharing of it in ways permitting horizontal interactivity across a crowd.
  • This definition would rule in content-mediated discussions at an unConference of BarCamp; and the intentional facilitation of a participative workshop using media content – be that multi-media or paper-based media.(I expect this set of examples to be more controversial – and ones that go beyond most people’s commonsense ideas of social media

For question tests, I believe this definition should facilitate the answering of questions such as:

  • Is social media a democratizing force?
  • How can social media be used in front line public services?
  • How do specific examples of social media structurally differ?
  • What properties of social media contribute to collaboration?
  • How can social media contribute to greater community building, rather than to greater individualism?

For questions about the properties of social media – the definition does not only pick out examples of social media, but also gives a framework for assessing different properties of social media – but I feel this is a justifiable bit of additional work done by the definition in this question context.

Use and development

This blog post (at is the first attempt at forming and sharing this definition. I will be giving it a practical test in at least one upcoming project – but wish to subject it to a wider critical test.

Perhaps, for purposes other than my own, it is a non-starter – and a definition that cannot achieve some wider than individual acceptance is little use at all. But I hope it can prove useful (in current, or a revised form) for others.

(All comments and feedback; pointers to other works etc. are welcome. Thanks to all who have contributed to conversations on this topic with suggestions of links to follow, or pointers to existing definitions also, and apologies that version 1 this blog post, written whilst I’ve been without Internet access, does not offer specific references and credits.)
