what was the first social media platform? Here’s everything that happened since

Most people assume the first social media platform was MySpace, or maybe Friendster. Both guesses are wrong by at least 6 years. The real answer is Six Degrees, a site that launched in 1997 and quietly laid the blueprint every platform after it would follow.

Here’s the full story, from 1997 to now.

Six Degrees: what was the first social media platform

Andrew Weinreich built Six Degrees and launched it in 1997. The name came from the “six degrees of separation” theory: the idea that any 2 people on earth are connected through at most 6 social links.

The site did 3 things. You could create a profile. List your friends. Browse their friend networks. That’s it. No video, no ads, no algorithm deciding what you saw. Just a map of who knew who.

It peaked at 3.5 million users. Then it shut down in 2001. The internet wasn’t ready, and the dial-up era wasn’t exactly built for social discovery.

But the architecture Weinreich designed, profile plus connections plus browsable network, is exactly what Facebook, LinkedIn, and Instagram all run on today. Every first social media platform historian points back to this moment as the origin.

The years between (1999–2003)

Six Degrees closing didn’t kill the idea. It just sat dormant for a few years.

LiveJournal launched in 1999. It was less “social network” and more public diary, but it introduced the concept of following strangers and commenting on their lives. Blogger arrived the same year. Neither was quite a social media platform in the modern sense, but both pushed the idea that regular people could broadcast their thoughts online.

Friendster showed up in 2002. It was the first post-Six Degrees network that actually felt like what we’d now call social media: profiles, photos, mutual connections. It grew fast, then collapsed faster, mostly because its servers couldn’t handle the traffic. 100 million users tried to load pages that took 40 seconds to render. People left.

The big bang: 2003–2006

This is when things accelerated.

LinkedIn launched in May 2003, specifically for professional networking. It’s still the dominant platform in that lane today.

MySpace arrived in August 2003 and became the defining social network of its era. At its peak in 2006, it had 100 million accounts. Tom Anderson, one of its founders, was everyone’s first friend by default, a detail an entire generation remembers.

Facebook launched in February 2004, initially just for Harvard students. Within a year it had expanded to other universities. By 2006 it was open to anyone with an email address. The rest is the entire modern internet.

YouTube launched in 2005 and went from startup to Google acquisition (for $1.65 billion) in 18 months. Video changed everything about what “social content” could mean.

Twitter came in 2006. 140 characters. Public by default. Chronological feed. It felt nothing like what had come before, and its influence on how public discourse works has been enormous (and argued about constantly).

The mobile shift: 2010–2015

The iPhone launched in 2007. By 2010, smartphones were everywhere, and social media redesigned itself around the pocket-sized screen.

Instagram launched in 2010 and hit 1 million users in 3 months. It was built for the phone camera: square photos, simple filters, double-tap to like. Facebook bought it in 2012 for $1 billion. At the time, people thought that was insane. Instagram is now worth roughly $100 billion.

Snapchat (2011) made content disappear by default. Pinterest (2010) organized the web visually. WhatsApp (2009) turned messaging into a global infrastructure. These weren’t marginal products. They reshaped how billions of people communicate.

The algorithm era: 2016–2020

Social media stopped showing you what your friends posted in order. Feeds became ranked by engagement, time-on-screen, and ad revenue potential. The shift was quiet and had massive consequences.

TikTok launched internationally in 2018. Its feed is entirely algorithmic: it shows you content from strangers, not friends. You don’t follow your way into a feed. The feed finds you. That’s a genuinely different model, and it’s now the dominant one. Every major platform has copied it to some degree.

By 2020, Facebook had 2.7 billion monthly users. Social media wasn’t a niche internet thing anymore. It was the public square.

Where we are in 2026

The landscape looks like this: TikTok is still the engagement leader despite ongoing regulatory fights in the US. Instagram, YouTube, and Facebook remain massive. X (formerly Twitter) has gone through a chaotic ownership change and lost significant advertiser trust, but still exists. Threads, Meta’s Twitter alternative, launched in 2023 and grew fast, then plateaued.

AI-generated content is now everywhere on every platform, which has created a strange situation: the first social media platform was built to show you real people you actually knew. In 2026, you often can’t tell if what you’re looking at was made by a person at all.

Twenty-nine years from Six Degrees to AI slop. Weinreich probably didn’t see that one coming.

Timeline: evolution of the first social media platform to now

Frequently Ask Question

What was the first social media platform ever created?

Six Degrees, launched in 1997 by Andrew Weinreich. It let users create profiles, list friends, and browse their connections. That makes it the first social media platform by the most widely accepted definition. It shut down in 2001 after failing to find a sustainable business model.

Wasn’t MySpace or Friendster the first social media platform?

Neither. Friendster launched in 2002 and MySpace in 2003, both 5-6 years after Six Degrees. They were more visible and more widely used, which is probably why people remember them first. But Six Degrees predates both.

How many users did the first social media platform have?

Six Degrees peaked at around 3.5 million registered users. For context, Facebook had 100 million by 2008 and passed 3 billion sometime around 2022. Six Degrees was tiny by modern standards, but it proved the concept worked.

Why did the first social media platform fail?

A few reasons. Dial-up internet made the experience slow. Smartphones didn’t exist, so you had to sit at a desktop to use it. And critically, most people didn’t have enough friends online yet to make the network feel worth using. It was the right idea at the wrong time.

Is Six Degrees still around?

No. It shut down in 2001. Weinreich sold it for $125 million in 2000, just before the dot-com crash. The new owners couldn’t make it profitable and closed it. A different site called SixDegrees.org launched later for nonprofit networking, but it’s unrelated to the original.

What is the most used social media platform in 2026?

By monthly active users, Facebook still leads with over 3 billion. YouTube is second. WhatsApp and Instagram are both around 2 billion. TikTok leads in time-spent-per-user metrics, particularly among younger demographics.

How did social media change between 1997 and 2026? The core model, profile plus connections, hasn’t changed since the first social media platform. What changed is scale (billions vs millions), medium (video dominates over text), monetization (advertising became the default), and feed logic (algorithmic ranking replaced chronological order). The bones are the same. Everything around them got bigger and stranger.
