Imagine working full-time while pouring your nights and weekends into a passion project with a few coworkers. It starts as a side hustle—just a small idea built out of curiosity and creativity. Fast forward five years, and that hobby has become one of the most transformative communication tools in modern history. That’s exactly how Twitter, now known as X, began its journey.
How Twitter Got Its Start
Twitter’s story started in 2006 when Jack Dorsey (@Jack) envisioned an SMS-based platform for sharing status updates. His idea was simple: let friends stay in touch by posting short, text-style messages about what they were doing. It was a new take on digital communication—like texting, but open and social.
The concept took shape during a brainstorming session at Odeo, a podcasting startup co-founded by Evan Williams (@Ev). Dorsey pitched the idea to Evan and Biz Stone, who encouraged him to explore it further. What started as an experiment quickly evolved into something far bigger.
In its earliest days, the platform was called “twttr.” At the time, omitting vowels was trendy among startups looking for unique domain names. Noah Glass, a developer on the team, is credited with naming it “twttr” and eventually suggesting the final name: Twitter.
The Very First Tweet That Started It All
On March 21, 2006, Jack Dorsey posted the first-ever tweet: “just setting up my twttr.” That short message marked the beginning of what would become a social media powerhouse. Years later, in 2021, this tweet was sold as an NFT for $2.9 million, reflecting the cultural and technological impact of the platform.
In the early stages, Twitter’s development team racked up high SMS bills while testing features. At the same time, Odeo’s core business was collapsing due to Apple launching its own podcast platform. In response, the founders decided to buy back Odeo from investors, regaining control and acquiring the Twitter project in the process.
This buyback gave Jack Dorsey, Evan Williams, Biz Stone (@Biz), and other team members full ownership of Twitter. However, the transition wasn’t without controversy. Some investors may not have been fully informed about Twitter’s potential, and key developers—like Noah Glass (@Noah)—were left out of the new company structure.
To formally house the project, the team created a new entity called the Obvious Corporation (@obviouscorp). From this point on, Twitter was officially a standalone platform ready to scale.
When Twitter Took Off: The Growth Era
Twitter’s breakout moment came at the 2007 South by Southwest (@sxsw) Interactive conference. The team showcased Twitter to attendees, resulting in a massive surge in usage—over 60,000 tweets were sent daily during the event. This exposure helped skyrocket the platform’s popularity.
As Twitter grew rapidly, it struggled to handle the load. Frequent outages plagued the site, and users were often greeted by an error page featuring a cartoon whale being lifted by birds—an illustration by artist Yiying Lu (@YiyingLu) that came to be known as the “Fail Whale.” This image became a cultural icon among early Twitter users.
Why Tweets Were Originally 140 Characters
Twitter’s tweet character limit has always been a defining feature. Originally capped at 140 characters, this constraint mirrored the SMS limits imposed by mobile carriers. While the limit stuck for branding reasons, Twitter eventually doubled it to 280 characters in 2017, recognizing that smartphones and modern communication had outgrown the original restriction.
Despite initial pushback, the character limit increase allowed users to express thoughts more clearly without breaking them into multiple tweets. Most tweets still hovered around 50 characters, but the flexibility gave users more room to speak without editing down their thoughts excessively.
How Users Shaped Twitter’s Features
Much of Twitter’s most important innovation came from its users. Without built-in replies, people began manually tagging others with the “@” symbol. This user behavior became so widespread that Twitter added official support. Hashtags and retweets followed a similar path, starting as user-invented hacks that were eventually baked into the platform.
Users began using “RT” to share someone else’s tweet while giving credit. By 2010, Twitter made retweeting a built-in feature. These grassroots innovations helped shape Twitter into a unique and flexible social network—driven largely by its community.
The Rise of Bots and Fake Accounts on Twitter
However, the platform wasn’t without problems. A 2020 research indicated that around 15% of Twitter accounts were bots. These bots were often responsible for fake engagement, misinformation, and spam. As bot activity grew, the platform’s credibility and user trust took a hit.
Elon Musk’s Takeover and Twitter’s Rebrand to X
In 2022, Elon Musk purchased Twitter for $44 billion, following a rocky negotiation. Musk initially tried to back out of the deal over concerns about bots, but ultimately the acquisition went through. His takeover marked the beginning of major changes—and significant turmoil.
Musk quickly slashed Twitter’s workforce, which led to instability across the platform. Outages became more frequent, moderation weakened, and bot issues worsened. These problems eroded user trust and drove many to explore Twitter alternative platforms.
Twitter also introduced Twitter Blue, a subscription service offering benefits like editable tweets, longer post limits, and algorithmic priority. Most controversially, the blue checkmarks—once reserved for verified accounts—were now tied to paid subscriptions, increasing impersonation risks and spreading misinformation.
As dissatisfaction grew, competitors like Threads, Bluesky, and Hive Social gained traction among users looking for a stable and reliable alternative. In 2023, Elon Musk announced that Twitter would officially rebrand as “X,” retiring the iconic bird logo and embracing a broader vision for the platform.
What began as a side project built on SMS technology evolved into a global communication tool that reshaped news, politics, and social interaction. Twitter’s transformation into X marks a new chapter—but its legacy remains rooted in user creativity, real-time connection, and cultural impact.
