Social media helps the development of online social networks by connecting a user's profile with those of other individuals or groups.[2][5]
The term social in regard to media suggests platforms enable communal activity. Social media enhances and extends human networks.[6] Users access social media through web-based apps or custom apps on mobile devices. These interactive platforms allow individuals, communities, and organizations to share, co-create, discuss, participate in, and modify user-generated or self-curated content.[7][5][1] Social media is used to document memories, learn, and form friendships.[8] They may be used to promote people, companies, products, and ideas.[8] Social media can be used to consume, publish, or share news.
Social media platforms can be categorized based on their primary function.
Social networking sites like Facebook and LinkedIn focus on building personal and professional connections.
Media sharing networks, including Instagram, TikTok, YouTube, and Snapchat, allow users to share images, videos, and live streams.
Discussion and community forums like Reddit, Quora, and Discord facilitate conversations, Q&A, and niche community engagement.
Live streaming platforms, such as Twitch, Facebook Live, and YouTube Live, enable real-time audience interaction.
Decentralized social media platforms like Mastodon and Bluesky aim to provide social networking without corporate control, offering users more autonomy over their data and interactions.
Social media outlets differ from old media (e.g. newspapers, TV, and radio broadcasting) in many ways, including quality,[9]reach, frequency, usability, relevancy, and permanence.[10] Social media outlets operate in a dialogic transmission system (many sources to many receivers) while traditional media operate under a monologic transmission model (one source to many receivers). For instance, a newspaper is delivered to many subscribers, and a radio station broadcasts the same programs to a city.[11]
Social media has been criticized for a range of negative impacts on children and teenagers, including exposure to inappropriate content, exploitation by adults, sleep problems, attention problems, feelings of exclusion, and various mental health maladies.[12][13] Social media has also received criticism as worsening political polarization and undermining democracy. Major news outlets often have strong controls in place to avoid and fix false claims, but social media's unique qualities bring viral content with little to no oversight. "Algorithms that track user engagement to prioritize what is shown tend to favor content that spurs negative emotions like anger and outrage. Overall, most online misinformation originates from a small minority of "superspreaders," but social media amplifies their reach and influence."[14]
