Social media outlets differ from [[old media]] (e.g. [[newspaper]]s, [[Television broadcaster|TV]], and [[radio broadcasting]]) in many ways, including quality,<ref name="qualitymedia">{{cite journal|last1=Agichtein|first1=Eugene|last2=Castillo|first2=Carlos|last3=Donato|first3=Debora|last4=Gionis|first4=Aristides|last5=Mishne|first5=Gilad|title=Finding high-quality content in social media|journal=WISDOM – Proceedings of the 2008 International Conference on Web Search and Data Mining|year=2008|pages=183–193|url=http://184pc128.csie.ntnu.edu.tw/presentation/09-03-09/Finding%20High-Quality%20Content%20in%20Social%20Media.pdf|access-date=8 January 2019|archive-date=23 May 2023|archive-url=https://web.archive.org/web/20230523090540/http://184pc128.csie.ntnu.edu.tw/presentation/09-03-09/Finding%20High-Quality%20Content%20in%20Social%20Media.pdf|url-status=dead}}</ref> [[Reach (advertising)|reach]], [[frequency]], usability, relevancy, and permanence.<ref name="Tao-2016">{{Cite journal|last1=Tao|first1=Xiaohui|last2=Huang|first2=Wei|last3=Mu|first3=Xiangming|last4=Xie|first4=Haoran|date=18 November 2016|title=Special issue on knowledge management of web social media|url=https://content.iospress.com/download/web-intelligence/web343?id=web-intelligence%2Fweb343|journal=Web Intelligence|volume=14|issue=4|pages=273–274|doi=10.3233/WEB-160343|via=Lingnan scholars}}</ref> Social media outlets operate in a ''[[dialogic]]'' transmission system (many sources to many receivers) while traditional media operate under a {{Wikt-lang|en|monologic}} transmission model (one source to many receivers).

==History==
{{see also|Timeline of social media}}

=== Early computing ===
The [[PLATO (computer system)|PLATO system]] was launched in 1960 at the [[University of Illinois at Urbana–Champaign|University of Illinois]] and subsequently commercially marketed by [[Control Data Corporation]]. It offered early forms of social media features with innovations such as Notes, PLATO's message-forum application; TERM-talk, its instant-messaging feature; [[Talkomatic]], perhaps the first [[online chat room]]; News Report, a [[crowdsourced]] online newspaper, and blog and Access Lists, enabling the owner of a note file or other application to limit access to a certain set of users, for example, only friends, classmates, or co-workers.

[[File:The IMP Log The Very First Message Sent on the Internet (6293913865).jpg|thumb|IMP log for the first message sent over the Internet, using ARPANET]]
[[ARPANET]], which came online in 1967, had by the late 1970s enabled exchange of non-government/business ideas and communication, as evidenced by the [[ARPANET#Rules and etiquette|network etiquette]] (or "[[netiquette]]") described in a 1982 handbook on computing at [[MIT]]'s [[MIT Computer Science and Artificial Intelligence Laboratory|Artificial Intelligence Laboratory]].<ref name="Stacy">{{cite web |last=Stacy |first=Christopher C. |date=September 7, 1982 |title=Getting Started Computing at the AI Lab |issue=Working Paper 235 |publisher=MIT Artificial Intelligence Laboratory |url=https://dspace.mit.edu/bitstream/handle/1721.1/41180/ai_wp_235.pdf?sequence=4 |url-status=live |archive-url=https://web.archive.org/web/20190323132534/https://dspace.mit.edu/bitstream/handle/1721.1/41180/AI_WP_235.pdf?sequence=4 |archive-date=2019-03-23 }}</ref> ARPANET evolved into the [[Internet]] in the 1990s.<ref>{{cite journal|url=https://www.rfc-editor.org/info/rfc0675|last1=Cerf|first1=Vinton|last2=Dalal|first2=Yogen|last3=Sunshine|first3=Carl|title=Specification of Internet Transmission Control Program |year=1974|journal=RFC|access-date=2022-08-29|page=675|doi=10.17487/RFC0675|doi-access=free}}</ref> [[Usenet]], conceived by [[Tom Truscott]] and [[Jim Ellis (computing)|Jim Ellis]] in 1979 at the [[University of North Carolina at Chapel Hill]] and [[Duke University]], was the first open social media app, established in 1980.

[[File:Koala Country Doors Menu.jpg|thumb|A bulletin board system menu, featuring [[opinion poll]]s and a "Who's been on today?" query]]
A precursor of the electronic [[bulletin board system]] (BBS), known as [[Community Memory]], appeared by 1973. Mainstream BBSs arrived with the Computer Bulletin Board System in Chicago, which launched on February 16, 1978. Before long, most major US cities had more than one BBS, running on [[TRS-80]], [[Apple II series|Apple II]], [[Atari Corporation|Atari]], [[IBM Personal Computer|IBM PC]], [[Commodore 64]], [[Sinclair Research|Sinclair]], and similar [[personal computer]]s. [[CompuServe]], [[Prodigy (online service)|Prodigy]], and [[AOL]] were three of the largest BBS companies and were the first to migrate to the Internet in the 1990s. Between the mid-1980s and the mid-1990s, BBSes numbered in the tens of thousands in North America alone.<ref name="Edwards-2016">{{cite web|last=Edwards|first=Benj| title= The Lost Civilization of Dial-Up Bulletin Board Systems| url= https://www.theatlantic.com/technology/archive/2016/11/the-lost-civilization-of-dial-up-bulletin-board-systems/506465/| work= The Atlantic| date= November 4, 2016| access-date=2018-02-05}}</ref> Message forums were the signature BBS phenomenon throughout the 1980s and early 1990s.

In 1991, [[Tim Berners-Lee]] integrated [[HTML]] [[hypertext]] software with the Internet, creating the [[World Wide Web]]. This breakthrough led to an explosion of [[blog]]s, [[Mailing list|list servers]], and [[email]] services. Message forums migrated to the web, and evolved into [[Internet forum]]s, supported by cheaper access as well as the ability to handle far more people simultaneously.

These early text-based systems expanded to include images and video in the 21st century, aided by [[digital cameras]] and [[camera phones]].<ref name="spinoff">{{cite web |year=2017 |title=CMOS Sensors Enable Phone Cameras, HD Video |url=https://spinoff.nasa.gov/Spinoff2017/cg_1.html |access-date=6 November 2019 |website=[[NASA Spinoff]] |publisher=[[NASA]]}}</ref>

=== Social media platforms ===
[[File:SixDegrees.com logo.png|thumb|[[SixDegrees.com|SixDegrees]], launched in 1997, is often regarded as the first social media site.]]
The evolution of online services progressed from serving as channels for networked communication to becoming interactive platforms for networked social interaction with the advent of [[Web 2.0]].<ref name="Dijck"/>

Social media started in the mid-1990s with the invention of platforms like [[GeoCities]], [[Classmates.com]], and [[SixDegrees.com]].<ref name="Ngak-2011">{{cite web |last=Ngak |first=Chenda |date=2011-07-06 |title=Then and now: a history of social networking sites |url=https://www.cbsnews.com/pictures/then-and-now-a-history-of-social-networking-sites/2/ |access-date=2018-01-26 |work=CBS news}}</ref> While instant messaging and chat clients existed at the time, SixDegrees was unique as it was the first online service designed for people to connect using their actual names instead of anonymously.

A 2015 review identified four features unique to social media services:<ref name="SMDefinition" />
* [[Web 2.0]] Internet-based applications.<ref name="SMDefinition" /><ref name="usersoftheworld" />
* [[User-generated content]]<ref name="SMDefinition" /><ref name="usersoftheworld" />

* [[Virtual world]]s ([[Second Life]], [[Twinity]])

Some services offer more than one type of service.<ref name="boydEllison" />

== Mobile social media ==
Mobile social media refers to the use of social media on [[mobile device]]s such as [[smartphone]]s and [[tablet computer|tablet]]s. It is distinguished by its ubiquity, since users no longer have to be at a desk in order to participate on a [[computer]]. Mobile services can further make use of the user's immediate location to offer information, connections, or services relevant to that location.

According to [[Andreas Kaplan]], mobile social media activities fall among four types:<ref name="mobileKaplan">{{cite journal |last=Kaplan |first=Andreas M. |date=March–April 2012 |title=If you love something, let it go mobile: Mobile marketing and mobile social media 4x4 |journal=Business Horizons |volume=55 |issue=2 |pages=129–139 |doi=10.1016/j.bushor.2011.10.009}}</ref>

* Space-timers (location and time-sensitive): Exchange of messages with relevance for a specific location at a specific point in time (posting about a traffic jam)
* Space-locators (only location sensitive): Posts/messages with relevance for a specific location, read later by others (e.g. a restaurant review)
* Quick-timers (only time sensitive): Transfer of traditional social media [[mobile apps]] to increase immediacy (e.g. posting status updates)
* Slow-timers (neither location nor time sensitive): Transfer of traditional social media applications to mobile devices (e.g. watching a video)

== Elements and function ==

=== Virality ===
{{Main|Viral phenomenon}}
Certain [[Content creation|content]] has the potential to spread ''virally'', an analogy for the way [[Viral disease|viral infections]] spread contagiously from individual to individual. One user spreads a post across their network, which leads those users to follow suit. A post from a relatively unknown user can reach vast numbers of people within hours. Virality is not guaranteed; few posts make the transition.

[[Viral marketing]] campaigns are particularly attractive to [[business]]es because they can achieve widespread advertising coverage at a fraction of the cost of traditional marketing campaigns<!-- newspapers, magazines, billboards, etc -->. [[Nonprofit organization]]s and [[Activism|activists]] may also attempt to spread content virally.

Social media sites provide specific functionality to help users re-share content, such as [[Twitter|X]]'s and [[Facebook]]'s "like" option.<ref>{{Cite arXiv|eprint=1106.0346|class=cs.SI|first=Rumi|last=Ghosh|title=Entropy-based Classification of 'Retweeting' Activity on Twitter|date=June 2011}}</ref>

=== Platform convergence ===
{{anchor|Scope expansion and feature merge}}<!--This keeps existing section links intact.-->

As an instance of [[technological convergence]], various social media platforms adapted functionality beyond their original scope, increasingly overlapping with each other.

Examples are the social hub site [[Facebook]] launching an integrated [[video platform]] in May 2007,<ref>{{cite web |first=Pete |last=Cashmore |title=Facebook Video Launches: YouTube Beware! |url=http://mashable.com/2007/05/24/facebook-video-launches/ |website=[[Mashable]] |date=May 25, 2007 |access-date=June 15, 2017}}</ref> and [[Instagram]], whose original scope was low-resolution photo sharing, introducing the ability to share quarter-minute 640×640 pixel videos<ref>{{cite web |title=Introducing Video on Instagram|date=2013-06-20|url=https://about.instagram.com/blog/announcements/introducing-video-on-instagram |publisher=Instagram|language=en}}</ref> (late extended to a minute with increased resolution). Instagram later implemented [[stories (social media)|stories]] (short videos self-destructing after 24 hours), a concept popularized by [[Snapchat]], as well as ''[[IGTV]]'', for seekable videos.<ref>{{cite web |url=https://animoto.com/blog/video-marketing/instagram-video-length |title=Instagram Video Length Guide (An Easy Cheat Sheet)|last=Livesay|first=Kari|date=2022-04-13|publisher=Animoto|access-date=2022-08-29}}</ref> Stories were then adopted by [[YouTube]].<ref>{{cite web |last1=Alexander |first1=Julia |title=YouTube is rolling out its Instagram-like Stories feature to more creators |url=https://www.theverge.com/2018/11/29/18117670/youtube-stories-creators-subscribers-instagram-philip-defranco |website=The Verge |language=en |date=29 November 2018}}</ref>

[[Twitter|X]], whose original scope was text-based microblogging, later adopted photo sharing,<ref>{{cite web |last1=Parr |first1=Ben |title=Twitter Rolls Out Photo Sharing to All Users |url=https://mashable.com/2011/08/09/twitter-photo-sharing-all/ |website=Mashable |language=en |date=Aug 10, 2011}}</ref> then video sharing,<ref>{{cite web |title=Now on Twitter: group Direct Messages and mobile video camera |url=https://blog.twitter.com/en_us/a/2015/now-on-twitter-group-direct-messages-and-mobile-video-capture.html|last=Kamdar|first=Jinen|publisher=Twitter|date=2015-01-27|language=en-us}}</ref><ref>{{cite web |title=New ways to tap into video on Twitter |url=https://blog.twitter.com/en_us/a/2016/new-ways-to-tap-into-video-on-twitter.html|publisher=Twitter|date=2016-06-21|last=Rishel|first=Jeremy|language=en-us |access-date=2022-08-29}}</ref> then a media studio for business users, after YouTube's Creator Studio.<ref>{{cite web |title=Twitter Updates Media Studio, Expands Access to All Users |url=https://www.socialmediatoday.com/social-business/twitter-updates-media-studio-expands-access-all-users |last=Hutchinson|first=Andrew|date=2017-03-15|publisher=Social Media Today|access-date=2022-08-29}}</ref>

The discussion platform [[Reddit]] added an integrated [[Image hosting service|image hoster]] replacing the external image sharing platform [[Imgur]],<ref>{{cite web |title=r/announcements - Image Hosting on Reddit |url=https://www.reddit.com/r/announcements/comments/4p5dm9/image_hosting_on_reddit/ |publisher=reddit |date=2016-06-21|access-date=2022-08-29}}</ref> and then an internal video hosting service,<ref>{{cite web |title=r/changelog - [Reddit change] Introducing video uploading beta |url=https://www.reddit.com/r/changelog/comments/6jo5it/reddit_change_introducing_video_uploading_beta/ |publisher=reddit |date=2017-06-26|access-date=2022-08-29}}</ref> followed by image galleries (multiple images in a single post), known from Imgur.<ref>{{cite web |title=Introducing Reddit Image Galleries |url=https://redditblog.com/2020/07/15/introducing-reddit-image-galleries-now-redditors-can-share-multiple-images-and-gifs-in-one-post/ |website=Upvoted |date=2020-07-15|url-status=dead|archive-date=2020-07-16|archive-url=https://web.archive.org/web/20200716191433/https://redditblog.com/2020/07/15/introducing-reddit-image-galleries-now-redditors-can-share-multiple-images-and-gifs-in-one-post/}}</ref> Imgur implemented video sharing.<ref>{{cite web |last1=Liao |first1=Shannon |title=Imgur adds 30-second video uploads so your GIFs can have soundtracks |url=https://www.theverge.com/2018/5/29/17406840/imgur-video-upload-unmuted-gifs-sound-on |website=The Verge |language=en |date=29 May 2018}}</ref><ref>{{cite web |title=How to Upload Video |url=https://help.imgur.com/hc/en-us/articles/360003632072-How-to-Upload-Video |website=Imgur|url-status=dead|archive-date=2019-06-13|archive-url=https://web.archive.org/web/20190613074923/https://help.imgur.com/hc/en-us/articles/360003632072-How-to-Upload-Video}}</ref>

===Usage: before the pandemic===
A 2009 study suggested that individual differences may help explain who uses social media: [[Extraversion and introversion|extraversion]] and [[openness]] have a positive relationship with social media, while [[emotional stability]] has a negative sloping relationship with social media.<ref>{{Cite journal|last1=Correa|first1=Teresa|last2=Hinsley|first2=Amber W.|date=October 2009|title=Who Interacts on the Web?: The Intersection of Users' Personality and Social Media Use|url=https://www.sciencedirect.com/science/article/pii/S0747563209001472|journal=Computers in Human Behavior|volume=26|issue=2|pages=247–253|doi=10.1016/j.chb.2009.09.003|s2cid=3748842 }}</ref> A 2015 study reported that people with a higher [[Social comparison bias|social comparison]] orientation appear to use social media more heavily than people with low social comparison orientation.<ref>{{cite journal|last1=Vogel|first1=Erin A.|last2=Rose|first2=Jason P.|last3=Okdie|first3=Bradley M.|last4=Eckles|first4=Katheryn|last5=Franz|first5=Brittany|year=2015|title=Who compares and despairs?

==== Reasons for use by adults ====
While adults were using social media before the [[COVID-19 pandemic]], more started using it to stay socially connected and to get pandemic updates. <blockquote>"Social media have become popularly use to seek for medical information and have fascinated the general public to collect information regarding corona virus pandemics in various perspectives.

==== Addiction ====
Social media platforms can serve as a breeding ground for addiction-related behaviors, with studies report that excessive use can lead to addiction-like symptoms. These symptoms include compulsive checking, mood modification, and withdrawal when not using social media, which can result in decreased face-to-face social interactions and contribute to the deterioration of interpersonal relationships and a sense of loneliness.<ref>{{cite journal|title=Meta-analyses of comparative efficacy of antidepressant medications on peripheral BDNF concentration in patients with depression|last1=Chanjuan|first1=Zhou|last2=Jiaju|first2=Zhong|last3=Bin|first3=Zou|last4=Liang|first4=Fang|last5=Jianjun|first5=Chen|last6=Xiao|first6=Deng|last7=Lin|first7=Zhang|last8=Xiang|first8=Zhao|last9=Zehui|first9=Qu|last10=Yang|first10=Lei|last11=Ting|first11= Lei|journal= PLOS ONE|year=2017|volume=12 |issue=2 |pages=e0172270 |doi=10.1371/journal.pone.0172270|pmid=28241064|pmc=5328267 |bibcode=2017PLoSO..1272270Z |doi-access=free }}</ref>

===Emotional effects===
One studied effect of social media is 'Facebook depression', which affects adolescents who spend too much time on social media.<ref name="Schurgin-2011" /> This may lead to reclusiveness, which can increase loneliness and low self-esteem.<ref name="Schurgin-2011">{{cite journal|last1=Schurgin O'Keeffe|first1=Gwenn|last2=Clarke-Pearson|first2=Kathleen|title=The impact of social media on children, adolescents, and families|date=2011|volume=127|issue=4|pages=800–804|doi=10.1542/peds.2011-0054|journal=Pediatrics|pmid=21444588 |s2cid=56801712 |url=https://pubmed.ncbi.nlm.nih.gov/21444588/}}</ref> Social media curates content to encourage users to keep scrolling.<ref name="Levenson 36–41"/> Studies report children's self-esteem is positively affected by positive comments and negatively affected by negative or lack of comments.

A second emotional effect is social media burnout, defined as ambivalence, emotional exhaustion, and [[depersonalization]]. Ambivalence is confusion about the benefits from using social media. Emotional exhaustion is stress from using social media. Depersonalization is emotional detachment from social media. The three burnout factors negatively influence the likelihood of continuing on social media.<ref>{{cite journal |last1=Han |first1=Bo |year=2018 |title=Social Media Burnout: Definition, Measurement Instrument, and Why We Care |journal=Journal of Computer Information Systems |volume=58 |issue=2 |pages=1–9 |doi=10.1080/08874417.2016.1208064 |s2cid=67791822}}</ref>

==== Australia ====
In July 2014, in response to [[WikiLeaks]]' release of a secret suppression order made by the [[Supreme Court of Victoria|Victorian Supreme Court]], media lawyers were quoted in the [[Australia]]n media to the effect that "anyone who tweets a link to the WikiLeaks report, posts it on Facebook, or shares it in any way online could also face charges".<ref>{{cite news |last=Cooper |first=Mex |date=July 30, 2014 |title=Social media users could be charged for sharing WikiLeaks story |url=http://www.brisbanetimes.com.au/national/social-media-users-could-be-charged-for-sharing-wikileaks-story-20140730-zye0b.html |access-date=2022-08-29 |publisher=[[Brisbane Times]]}}</ref>

In the [[2014 Thai coup d'état]], the public was explicitly instructed not to 'share' or 'like' dissenting views on social media or face prison.{{Citation needed|date=July 2024}}

==== United States ====
Historically, platforms were responsible for moderating the content that they presented. They set rules for what was allowable, decided which content to promote and which to ignore. The US enacted the [[Communications Decency Act]] in 1996. [[Section 230]] of that act exempted internet platforms from legal liability for content authored by third parties.
{{Blockquote|text=No provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider." (47 U.S.C. § 230(c)(1)).|author=US Congress|title=Communications Decency Act Section 230}}In 2024, legislation was enacted in [[Florida]] requiring social media companies to verify the age of people with accounts, and to prohibit holding an account for people aged under 14, and between 14 and 16 in the absence of parental approval.<ref>{{Cite web |last1=Hatter |first1=Lynn |last2=Andrews |first2=Adrian |date=2024-03-25 |title=DeSantis signs social media ban for minors, among the strictest in the nation |url=https://health.wusf.usf.edu/health-news-florida/2024-03-25/desantis-signs-social-media-ban-for-minors-among-the-strictest-in-the-nation |access-date=2024-05-29 |website=Health News Florida |language=en}}</ref><ref>{{Cite news |last= |first= |date=2024-03-26 |title=Ron DeSantis signs Florida social media ban for children into law |url=https://www.theguardian.com/us-news/2024/mar/26/ron-desantis-florida-social-media-ban-children |access-date=2024-07-30 |work=The Guardian |language=en-GB |issn=0261-3077}}</ref>

The [[European Union]] initially took a similar approach.<ref>{{Cite journal |last=Schlag |first=Gabi |date=2023-08-31 |title=European Union's Regulating of Social Media: A Discourse Analysis of the Digital Services Act |url=https://www.cogitatiopress.com/politicsandgovernance/article/view/6735 |journal=Politics and Governance |language=en |volume=11 |issue=3 |pages=168–177, p. 168 |doi=10.17645/pag.v11i3.6735 |issn=2183-2463 |doi-access=free }}</ref> However, in 2020, the [[European Commission]] presented two legislative proposals: The [[Digital Services Act|Digital Services Act (DSA)]] and the [[Digital Markets Act|Digital Markets Act (DMA)]]. Both proposals were enacted in July 2022. The DSA entered into force on 17 February 2024, the DMA in March 2024.<ref>{{Cite web |date=2023-11-15 |title=The Digital Services Act package {{!}} Shaping Europe's digital future |url=https://digital-strategy.ec.europa.eu/en/policies/digital-services-act-package |access-date=2023-11-26 |website=digital-strategy.ec.europa.eu |language=en}}</ref> This legislation can be summarized in the following four objectives, articulated by [[Member of the European Parliament|MEPs]]:

* "What is illegal offline must also be illegal online".<ref>{{Cite journal |last=Schlag |first=Gabi |date=2023-08-31 |title=European Union's Regulating of Social Media: A Discourse Analysis of the Digital Services Act |url=https://www.cogitatiopress.com/politicsandgovernance/article/view/6735 |journal=Politics and Governance |language=en |volume=11 |issue=3 |pages=168–177 |doi=10.17645/pag.v11i3.6735 |issn=2183-2463 |doi-access=free }}</ref>
* "Very large online platforms" must therefore, among other things 
** delete illegal content (propaganda, election interference, hate crimes and online harms such as harassment and child abuse) and better protect fundamental rights
** redesign their systems to ensure a "high level of privacy, security and protection of minors", by prohibiting advertising based on personal data, designing recommender systems to minimize risks for children and demonstrating this to the [[European Commission]] via a risk assessment, and 
** not use sensitive personal data such as race, gender and religion to target advertising.<ref>{{Cite news |last=O'Carroll |first=Lisa |date=2023-08-25 |title=How the EU Digital Services Act affects Facebook, Google and others |language=en-GB |work=The Guardian |url=https://www.theguardian.com/world/2023/aug/25/how-the-eu-digital-services-act-affects-facebook-google-and-others |access-date=2023-11-26 |issn=0261-3077}}</ref>

The DSA allows a country to require information to be deleted that is illegal only in that jurisdiction. According to Patrick Breyer from the [[German Pirate Party]], a problem could arise from the Hungarian government requesting a video to be deleted that is critical of Victor Orban, as he foresaw the potential for such determinations to be applied EU-wide.<ref>{{Cite web |last=Beckmann |first=Holger |title=Digital Services Act: Was illegal ist, muss raus aus dem Netz |url=https://www.tagesschau.de/ausland/europa/digital-services-act-100.html |access-date=2023-11-26 |website=tagesschau.de |language=de}}</ref>

== Business models ==
The business model of most social media platforms is based on selling slots to advertisers. Platforms provide access to data about each user, which allows them to deliver adds that are individually relevant to them. This strongly incents platforms to arrange their content so that users view as much content as possible, increasing the number of ads that they see. Platforms such as X add paid user subscriptions in part to reduce their dependence on advertising revenues.<ref>{{Cite web |last=L |first=Frank |date=March 1, 2023 |title=5 Winning Social Media Business Models + Examples |url=https://getstream.io/blog/social-media-business-models/ |access-date=2024-05-28 |website=getstream.io |language=en}}</ref>

Social media has become a regular source of news and information. A 2021 Pew Research Center poll reported roughly 70% of users regularly get news from social media,<ref name="Fuchs-2017" /> despite the presence of [[fake news]] and misinformation. Platforms typically do not take responsibility for content accuracy, and many do not vet content at all, although in some cases, content the platform finds problematic is deleted or access to it is reduced.<ref>{{Cite news |date=February 12, 2020 |title=Facebook starts fact-checking partnership with Reuters |newspaper=Reuters |url=https://www.reuters.com/article/us-facebook-partnership-reuters-idUSKBN2062K4 |access-date=March 2, 2022 }}</ref><ref>{{Cite magazine |last=Watercutter |first=Angela |title=Two to Tango: Twitter Fact-Checks the Fact-Checkers |url=https://www.wired.com/story/trump-speech-twitter-fact-check/ |magazine=Wired |access-date=March 2, 2022}}</ref><ref>{{Cite web |title=See fact checks in YouTube search results - YouTube Help |url=https://support.google.com/youtube/answer/9229632?hl=en |access-date=March 2, 2022 |website=support.google.com}}</ref> Content distribution algorithms otherwise typically ignore substance, responding instead to the contents' virality.

===Critique of activism===
{{Further|Social media activism}}
[[Malcolm Gladwell]] considers the role of social media in revolutions and protests to be overstated. He concluded that while social media makes it easier for [[Digital rhetoric|activists]] to express themselves, that expression likely has no impact beyond social media. What he called "high-risk activism" involves strong relationships, coordination, commitment, high risks, and sacrifice.<ref name="Gladwell 2010-10-04">{{cite magazine |last=Gladwell |first=Malcolm |date=October 4, 2010 |title=Small Changes – Why the revolution will not be tweeted |url=http://www.newyorker.com/magazine/2010/10/04/small-change-3 |access-date=2012-11-15 |magazine=[[The New Yorker]]}}</ref> Gladwell  claimed that social media are built around weak ties and argues that "social networks are effective at increasing participation—by lessening the level of motivation that participation requires."<ref name="Gladwell 2010-10-04" /> According to him, "Facebook activism succeeds not by motivating people to make a real sacrifice, but by motivating them to do the things that people do when they are not motivated enough to make a real sacrifice."<ref name="Gladwell 2010-10-04" />

Disputing Gladwell's theory, a 2018 survey reported that people who are politically expressive on social media are more likely to participate in offline political activity.<ref>{{Cite journal|last1=Kwak|first1=Nojin|last2=Lane|first2=Daniel S|last3=Weeks|first3=Brian E|last4=Kim|first4=Dam Hee|last5=Lee|first5=Slgi S|last6=Bachleda|first6=Sarah|date=April 1, 2018|title=Perceptions of Social Media for Politics: Testing the Slacktivism Hypothesis|journal=Human Communication Research|volume=44|issue=2|pages=197–221|doi=10.1093/hcr/hqx008|issn=0360-3989}}</ref>

Social media often features in political struggles. In some countries, [[Internet police]] or [[secret police]] monitor or control citizens' use of social media. For example, in 2013 some social media was banned in [[Turkey]] after the Taksim [[Gezi Park protests]]. Both X and YouTube were temporarily suspended in the country by a court's decision. A law granted immunity to Telecommunications Directorate (TİB) personnel. The TİB was also given the authority to block access to specific websites without a court order.<ref>{{cite web|first=Salih|last=Sarıkaya |title=Social Media Ban In Turkey: What Does It Mean? by Salih Sarıkaya |url=http://www.salihsarikaya.com/en/social-media-ban-in-turkey-what-does-it-mean-by-salih-sarikaya/ |date=October 30, 2014 |url-status=dead |archive-url=https://web.archive.org/web/20141006012638/http://www.salihsarikaya.com/en/social-media-ban-in-turkey-what-does-it-mean-by-salih-sarikaya/ |archive-date=2014-10-06 }}</ref> Yet TİB's 2014 blocking of [[Twitter|X]] was ruled by the constitutional court to violate free speech.<ref>{{Cite news|url=https://www.reuters.com/article/us-turkey-twitter-ban-idUSBREA311BF20140402 |title=Turkey's Twitter ban violates free speech: constitutional court |work=Reuters |date=April 2, 2014|access-date=2022-08-29}}</ref>
