The social media site Twitter is founded.

Twitter’s history begins in 2006, when it was created by Jack Dorsey, Noah Glass, Biz Stone, and Evan Williams. Initially developed as a side project at Odeo—a podcasting company—the idea was to create an SMS-based communication platform. Jack Dorsey posted the first tweet on March 21, 2006, saying “just setting up my twttr.” The name “twttr” was inspired by Flickr and the trend of dropping vowels in startup names at the time. What set Twitter apart early on was its simplicity: 140-character messages called “tweets” that could be shared instantly with followers. The service officially launched to the public in July 2006 and began to gain traction, especially at events like SXSW in 2007, where usage spiked dramatically.

As Twitter evolved, so did its influence. By the 2010s, it had become a major platform for real-time news, social commentary, and political discourse. Events like the Arab Spring in 2010-2012 showed how Twitter could be used to organize protests and amplify grassroots voices. Celebrities, politicians, and brands embraced it as a direct channel to communicate with the public. The character limit shaped communication styles, encouraging brevity and creativity. In 2017, the character limit was expanded to 280 characters, a move that reflected changes in how people used the platform without completely abandoning its roots.

Twitter also became a battleground for misinformation, harassment, and political polarization. During the 2016 U.S. presidential election, it was used heavily for both campaigning and the spread of disinformation, drawing scrutiny from governments and watchdog groups. Efforts to moderate content—like banning abusive accounts or labeling misleading information—were often controversial. The platform struggled to balance free expression with the need for healthy discourse. Meanwhile, its user base continued to grow, and it became an indispensable tool for journalists, activists, and everyday users alike.

In 2022, Twitter underwent one of its most dramatic changes: Elon Musk acquired the company for $44 billion. This marked a significant turning point. Musk quickly made sweeping changes—laying off large portions of the staff, altering moderation policies, and shifting the platform’s verification system. In 2023, the company was rebranded as “X,” signaling a broader vision to transform it into an “everything app.” The rebrand and internal changes were met with both enthusiasm and skepticism, and the platform’s future direction remains a subject of intense debate. Despite all the upheaval, Twitter—now X—continues to be one of the most influential social media platforms globally.
