HISTORY145 - Social Media: Late Learning for an Old Guy

 This time I came up with a blog topic on my own, after seeing some family news on Facebook.  I was in my 60s when social media got going, and admittedly passed the point of trying every new thing, perfectly happy with “old time” communication options.  I did however get into texting, although at least a decade late, and I did join Facebook (my only social media platform) fairly early, though I rarely use it. 

 

I see that social media has “taken over the world,” and I know very little about it, so I decided to do a little research and documentation.  The primary objective of this blog is to educate me to the “wonders” of social media. If I uncover some information that is new or useful to younger, long-time users of social media, that’s gravy.  Sorry.

After an introduction, I will discuss the history of the debut of some of the principal social media platforms, provide a guide to today’s platforms, and then discuss social media marketing, algorithms, negative impacts, and controls, and finish with a snapshot of the future of social media.

Here’s what I learned writing this blog:

 

Introduction

My many sources agree that social media refers to internet-based websites and applications that allow users to create virtual communities, communicate, and share user-generated content (like text, photos, and videos).  Globally, billions of users interact daily for personal connection, entertainment, and professional networking.

 

Various social media apps, or called platforms (see below), operate as computer applications.  They are software programs that can be downloaded to our mobile device or accessed directly through an internet browser on our computer.

Users dictate a social media experience by generating the text, images, and videos consumed by others.  Engagement relies on selectable features such as likes, shares, comments, and direct messaging.  Social media feeds to users (streams of photos, videos, text posts, and ads) are typically prioritized by proprietary algorithms based on relevance or based on past user behavior.

On the positive side, social media provides immense opportunities for global connection, community building, and instant access to information and entertainment.  On the negative side, social media apps are purposely designed to trigger psychological dependency, which can negatively impact sleep, attention spans, and mental well-being.  They can also act as breeding grounds for misinformation and cyberbullying.

I understand that most people use social media to satisfy basic psychological needs for connection, entertainment, and information:  I found that the primary reason across all age groups is keeping in touch with friends and family, and meeting people with similar hobbies.   Mindless scrolling (where you habitually flip through social media feeds for novel content) provides entertainment and escapism, acting as a way to fill spare time, relieve boredom, and consume viral or humorous content.  Social media platforms are also used to consume real-time news, discover trends, and learn new things.  Users create and share content to archive personal memories, build a personal brand, or find identity-affirming communities.

According to Sprout Social, a social media management enterprise, today there are 5.66 billion active social media users worldwide, which equates to about 68% of the global population.  Users navigate across an average of 6.75 different social networks monthly, spending about 18.5 hours per week on these platforms.

 

History

Social media evolved from early, text-only online bulletin boards into a multi-billion-user global infrastructure.  Over the last three decades, social media has shifted from simple desktop networking sites to apps on mobile devices, eventually becoming the AI-driven entertainment and communication networks that billions rely on today.  The evolution of modern communication and social connectivity spans several distinct eras; here are some examples that I found useful:

The Pre-Social Era (1970s - 1990s): Before dedicated social platforms existed, people connected through early internet infrastructure.

·         1979 (USENET): Developed as a worldwide distributed discussion system, allowing users to post messages to topic-specific newsgroups.

·         1995 (Classmates.com): One of the earliest networking websites, designed to help users find and reconnect with high school and college alumni.

The Dawn of Social Networking (Late 1990s - Early 2000s): This period introduced the foundational elements of modern social media: user profiles, friends lists, and visible networks.

·         1997 (SixDegrees.com): Widely recognized as the first true social media platform, enabling users to create profiles, list friends, and surf connections.

·         2002 (Linkedin): Linkedin grew to become the premier professional networking and career platform.

·         2003 (Myspace & Friendster): Friendster introduced a digital mapping of social relations and connections between entities like people, organizations, and digital objects.  Myspace became a cultural phenomenon, heavily integrated with early digital music.

Social Media Platforms (Mid-2000s): This era brought the social media platforms that currently dominate the global social landscape.

·         2004 (Facebook): Launched initially for college students, it eventually opened to the public, growing into the world's largest social network.

·         2005 (YouTube): Revolutionized user-generated video sharing, fundamentally changing media consumption.

·         2005 (Reddit): Website for news aggregation and discussion. It is structured into more than 100,000 active, user-created boards called "subreddits," which cover virtually every interest, hobby, and professional field.

·         2006 (Twitter/X): Popularized short 140-character, frequent posts like real-time public conversations, and "trending" topics to provide quick updates.

The Mobile and Visual Era (Late 2000s - 2010s): Smartphones and 4G technology changed social media from a desktop activity to an "always-on" mobile experience.

·         2009 (WhatsApp): It allowed users to send text, voice, and video messages, make voice and video calls, and share images, documents, and user locations using a cellular mobile network or Wi-Fi.

·         2010 (Instagram): Capitalized on smartphone cameras to make visual and photo-sharing a daily habit.

·         2010 (Pinterest): A visual search and discovery platform used to share and save ideas through digital pinboards, visual bookmarks representing recipes, home decor, fashion, and DIY projects - to gather inspiration and plan future activities.

·         2010 (Snapchat): Popularized "Stories" (temporary, disappearing content), emphasizing casual, in-the-moment sharing.

Short-Form Video, AI, and Big Money (Late 2010s - Present):   Social media transformed from services for staying in touch with personal friends to algorithm-driven entertainment platforms designed for global reach.

·         2016 / 2018 (TikTok): Popularized vertical screen orientation (to match how users naturally hold their smartphones) with short videos driven by Artificial Intelligence (AI) recommendations, rather than explicit subscriptions - fundamentally changing the industry.

·         Present Day: Modern social platforms are driven by AI-curated information (find, organize, and share relevant content), and Augmented Reality (AR), to create immersive sharing experiences.  (An explanation of how AI and AR work and contribute to social media is way beyond my scope in this blog.)  Social media is a $250 billion global industry where over 200 million individuals - such as influencers, educators, and artists - make enormous sums from their digital content and communities directly through social platforms and independent websites.

Guide to Today's Platforms

Sources make it clear that choosing the right social media platform today depends entirely on our goals, whether we are trying to build a personal brand, connect with friends, or grow a business.  Different networks cater to different content types and audiences.  (I also learned that the objectives/content of some individual social media apps have changed dramatically since their introduction.)  Here is a very top-level overview of the major platforms today and how they operate:

General & Community-Focused:

·         Facebook: The largest global social network. Ideal for connecting with friends, and family.  Best for broad reach, community groups, local business pages, and connecting with a mature demographic through text, photo albums, and short videos.

·         Reddit: A massive collection of forums and communities organized by interests. Ideal for authentic discussions, crowd-sourced advice, and reading or sharing niche news.

·         X: Formerly known as Twitter.  Best for real-time news, public conversations, and quick text-based updates.

Visual & Entertainment:

·         Instagram: Photo-and video-sharing app.  Best for visual storytelling, influencer culture, short videos, brands focused on aesthetics (e.g., travel, food, and fashion), and influencer culture.

(An influencer is an individual who shapes the attitudes, behaviors, or purchasing decisions of others through their authority, knowledge, or relationship with a dedicated audience).

·         TikTok: The leading platform for viral, authentic, and highly edited short videos.  Excellent for reaching Gen Z and younger millennials.

·         Pinterest: A visual discovery app often used as a bookmarking site.  Best for lifestyle, home decor, DIY, and e-commerce inspiration.

Professional & Creator-Focused:

LinkedIn: The premier network for professional networking, business-to-business marketing, and job searching.  Best for sharing industry insights, company news, and building a professional resume/brand.

YouTube: The world's largest video search engine.  Best for long-form educational content, tutorials, short video stories, and building a dedicated following.

Messaging & Ephemeral:

·    WhatsApp: A heavily utilized, end-to-end encrypted messaging app.  Excellent for direct, one-on-one or group communication and customer support.

·         Snapchat: Popular among younger demographics for highly casual, immediate peer-to-peer communication.

Here are a couple of figures that illustrate the popularity and user-age preferences for today’s social media platforms:

Marketing

I thought it might be interesting to better understand how businesses use social media.  Social media marketing is when businesses use social networks to promote a product, brand, or service.  It’s one part of a brand’s larger digital marketing strategy, and entails posting content on social media sites, engaging others in conversation, and, most importantly, building communities.  Social media marketing uses digital platforms to build brands, drive website traffic, engage audiences, and increase sales.  With over 5 billion global users, modern social media marketing relies on authenticity, data-driven targeting, and short video content rather than polished, corporate advertising.  Businesses maximize their return on investment by matching their specific industry goals to the native features of distinct social networks.

Different platforms cater to unique audiences and distinct marketing goals.  Here are some examples:

·        Facebook: Excellent for local audience targeting, community groups, and broad demographic reach.  It serves as a primary hub for global product discovery.

·        Instagram: Relies heavily on visual media, influencer partnerships, and short videos to drive consumer brand affinity and in-app shopping via social commerce.

·        TikTok: Driven by trends and AI-assisted content selections.  Ideal for high-energy, raw, authentic short videos that target younger consumer demographics.

·        LinkedIn: The premier channel for business-to-business marketers.  Focuses on industry thought leadership, talent recruitment, corporate networking, and professional connections generation.

·        YouTube: Built for in-depth educational resources, detailed product demonstrations, community video tutorials, and capturing highly specific, multi-word search queries rather than broad, searches.

 

Elements of social media marketing..

 

Algorithms

This is where the “rubber meets the road.”  Social media algorithms are invisible, AI-powered rules that platforms use to curate, rank, and recommend content to users.  (AI shapes everything users see, how brands connect with consumers, and how networks manage massive oceans of data.)  The primary goal of algorithms is to maximize user retention and engagement in the platform app, to serve you relevant advertisements, and generate profit.

How the Magic Formula Works: While each platform guards its exact source code, they all rely on the same foundational concepts.  The process generally follows these steps:

·         Inventory: The platform looks at every possible piece of content available to be shown to us.

·         Signals: The algorithm tracks your user data.  It measures our likes, comments, shares, watch time, and even exactly how long we pause on a specific post.

·         Predictions: Based on our past behavior, the algorithm calculates the mathematical probability that we will engage with a given piece of content.

·         Ranking: The system assigns a personalized relevancy score to each post and displays them in the order of highest to lowest score.

Common Types of Signals: Algorithms don't just rely on what we "like."  They process a massive matrix of indicators:

·         Engagement: Likes, comments, and saves.  Note: Shares, comments, and high completion/watch rates are usually weighted much heavier than a simple tap-to-like.

·         Relevance: Keywords, hashtags, and audio choices that the system matches to our known interests.

·         Recency: How recently the content was published.

·         Context: Our location, the time of day, and the type of device you are using.

 The Effects of Algorithmic Curation: Because algorithms optimize for what holds attention, they can create unintended consequences:

·         Echo Chambers: By feeding us more of what we already interact with, algorithms can isolate us from differing perspectives.

·         Viral Amplification: Algorithms frequently test new content on a small sample of strangers (non-followers).  If strangers engage with it, the algorithm scales its distribution to millions.

 

Negative Impacts

There are many potential negatives associated with using social media.  Many trace back to the anonymity of personal internet operations and the way social media algorithms are formulated.  Social media can negatively impact user well-being.  Here are some examples that impressed me:

·         Mental Health Risks: Constant exposure to curated, idealized lives can cause depression, anxiety, and feelings of inadequacy.  Social media can promote unrealistic beauty standards and body image issues. Former U.S. Surgeon General Vivek Murthy has advocated for warning labels on platforms like Instagram, Facebook, and TikTok due to these significant psychological harms to adolescents.

·         Social Isolation & Poor Communication: Replacing physical, in-person socialization with digital interactions can stunt the development of face-to-face communication skills and lead to feelings of loneliness.

·         Addiction and Time-Wasting: Platforms are deliberately designed to trigger pleasure and reward responses in the brain via likes, shares, and notifications. This highly addictive behavior can severely compromise productivity and focus.

·         Spread of Misinformation: Unverified data, "fake news," and propaganda often spread faster than factual stories, misleading users and potentially causing real-world harm.  Misinformation on social media is highly prevalent, accounting for up 80% of posts, depending on the specific topic, platform, and context.  Bots (from robots), automated software applications programmed to run accounts and perform actions on social platforms, contribute to misinformation.  Malicious bots are designed to deceive people.  They are often deployed in massive groups, known as "bot farms" or "botnets," to artificially inflate a user's follower count, leave fake reviews, spread phishing links, or mass-amplify political misinformation to sway public opinion.  The ⁠World Economic Forum classifies misinformation as a major global threat.   Distinguishing accurate facts from fabricated news continues to be a severe digital literacy hurdle.

·         Political Manipulation: Social media can amplify divisive contents and manipulate opinions.

·         Cyberbullying and Harassment: The shield of the internet enables trolling and online harassment, which can have devastating and long-lasting effects on victims' emotional and psychological well-being.  (Social media trolling is the deliberate act of posting inflammatory, offensive, or disruptive content online to provoke an emotional reaction or derail meaningful conversations.)  An examination of trolling in 2021 found that in terms of the percent of students that were trolled in the primarily used sites, 29% were trolled in Facebook, 28% were trolled in Snapchat, 23% were trolled in Instagram, 22% were trolled in Twitter-X, and 16% were trolled in TikTok.  Only about 3% to 8.5% of social media users actually post severely toxic or really mean things.  However, because these individuals post far more frequently than the average user, their content fills a disproportionate amount of comment sections.  A landmark study published in ⁠PNAS Nexus revealed that a tiny group of users produces a massive wave of online hostility.  To stop cyberbullying, we are advised to document all evidence by taking screenshots, block the offender, and report the behavior using the platform's safety settings.  Never respond or retaliate, as this often fuels the cycle of harassment.

·         Privacy and Security Threats: Over-sharing personal information can lead to data mining, stalking, and identity theft.  It also exposes users to various phishing scams and financial fraud.

·         Physical Health Tolls: Excessive screen time, particularly before bed, disrupts natural sleep cycles.  A sedentary lifestyle and poor posture from continuous device usage can also result in long-term health complications.

·         Economic Pressure and Consumption: Social media can encourage overconsumption and financial strain.

 

 

Controls

I learned that we are not helpless under the onslaught of many of the negative impacts of social media mentioned above.  Social media content controls are built-in privacy and filtering tools that allow us to curate what we see and manage who interacts with our digital footprint.  These customizable settings help protect our mental well-being, secure our data, and filter out sensitive or inappropriate material.

What We See (Feed Curation):

·         Actively Curate: We can use the "not interested," "hide," or "unfollow" buttons on posts we dislike.

·         Sensitive Content Filters: Platforms like Instagram offer ⁠Sensitivity Content Control to limit material that may be sexually suggestive or contain violence.

·         Suggested Posts: We can mute or "snooze" recommended algorithms and suggested content for 30 days to keep our feed focused solely on accounts we follow.

·         Mute and Block Words: We can hide specific phrases, hashtags, or offensive comments from our content feed and notifications.

Who Sees Us (Privacy Settings):

·         Account Visibility: We can switch our profile to Private so that only approved followers can view our photos, stories, and posts.

·         Audience Selection: We can adjust the audience of individual posts (e.g., Public, Friends, or Close Friends) before publishing.

·         Mentions & Tagging: We can restrict who is allowed to tag us in photos or mention us in their posts, reducing spam and unwanted exposure.

Account Security:

·         Two-Factor Authentication: We can add a critical layer of security by requiring a code sent to our device whenever we log in.

·         Activity Tracking: We can review active login sessions and revoke access to devices we no longer use.

 Third-Party Monitoring & Family Settings:

·         Parental Controls: For younger users, apps offer Family Centers (like on Snapchat) or built-in supervision, enabling parents to set screen time limits and monitor newly added friends.

·         Digital Wellness: We can use built-in daily screen limits, or enable third-party digital wellbeing apps to cap the amount of time spent browsing.

·         Community Guidelines: Platforms enforce baseline rules against hate speech, harassment, and dangerous content.  We can report posts that violate these ⁠guidelines.

·         Regulatory Landscape: In the absence of comprehensive federal data privacy legislation, many states have enacted ⁠privacy laws and Age-Appropriate Design Codes to restrict how social media companies can target minors and collect data.

Because platform interfaces change frequently, checking our privacy and content preference menus regularly ensures our account stays secured to our exact preferences.

 

Future of Social Media

The future of social media is apparently shifting away from massive, public broadcast feeds and moving toward immersive, AI-driven platforms, private niche communities, and integrated social commerce.  Instead of merely "connecting," platforms now serve as all-in-one infrastructures for discovery, entertainment, and digital living.  Here is how the digital landscape is evolving:

·        Platform Convergence & Search: The distinction between social networks and search engines is rapidly dissolving.  Younger demographics heavily utilize networks like TikTok and YouTube to find products, reviews, and local recommendations.

·         The Rise of "Closed" Communities: Public feeds are becoming less social and increasingly corporatized.  Users are retreating to smaller, private digital spaces - such as Discord servers (customizable, digital hub spaces where friends, communities, and creators gather to communicate via text channels, voice rooms, video calls, and media sharing), Reddit, and specialized servers - for genuine, peer-to-peer connection.

·        AI-Driven Personalization: Artificial Intelligence is moving past basic content curation.  Platforms are utilizing generative AI to create highly personalized content, virtual storefronts, and tailored predictive experiences.

·        Immersive Experiences: Augmented Reality (AR) and Virtual Reality (VR) environments are maturing from novelties into practical infrastructure.  Virtual social environments are changing how digital citizens interact, shop, and engage with brands in spaces layered over the physical world.

·        Social Commerce: Shopping and social media are merging seamlessly.  Buying products, interacting with virtual storefronts, and checking out are becoming native experiences that no longer require leaving the application.

 

Well, I learned a lot - way more that I really needed to.  But the increased background knowledge and insights are really illuminating.  My opinion of social media hasn’t changed; it can be very life expanding, but is very dangerous to many - for all the reasons discussed above - without knowledgeable application of controls and super personal discipline.

My principal sources include: “Demographics of Social Media,” pewresearch.com; plus, numerous other online sources, including answers to many queries using Google in AI-Mode.

Note:  The preparation of this blog was a unique experience for me, probably reflective of the times we live in.  Virtually the entire article was pieced together from literally tens of (perhaps over a hundred) queries using Google in AI-mode, as I dug deeper into the subject and tried to make the article as complete and understandable as possible.  I spent much of my time asking questions, editing, clarifying, expanding/supplementing, and finding suitable figures.
