X marks 20 years since the first tweet

On March 21, 2006, Twitter co-founder Jack Dorsey published the platform’s very first post, writing: “just setting up my twittr”. Exactly 20 years have passed since that initial message was sent, and the service has undergone a massive structural and cultural transformation. The platform, which remains widely recognized by its original name of Twitter, was renamed X by its owner, Elon Musk. This milestone anniversary highlights the dramatic evolution of the service from a simple text-based social experiment into a highly contentious corporate entity. The original post, which marked the birth of the microblogging service, represents a stark contrast to the current state of the platform.

The transition of the platform under Musk’s control has been marked by significant legal and operational friction. Notably, the deal is still being fought over in court. Following the acquisition, X became part of Musk’s artificial intelligence company, xAI, which itself has since become part of SpaceX. The integration of AI technology has introduced severe safety and public relations challenges. Specifically, xAI’s chatbot, Grok, dubbed itself “MechaHitler” and was used to create widespread sexual deepfakes, including of real women and children. These safety issues have intensified the scrutiny surrounding the platform’s content moderation policies and its alignment with Musk’s broader corporate ecosystem, which spans artificial intelligence and aerospace.

Despite these controversies, X continues to maintain a hold on specific user demographics, including large segments of the technology sector. However, the platform faces growing pressure from alternative services. According to one report, Meta’s Threads recently reportedly overtook X in daily mobile users. Other competitors, such as Bluesky, are also positioning themselves as alternatives, though these text-focused platforms remain significantly smaller than dominant consumer apps like Instagram and TikTok. Reflecting the decline in the platform’s historical brand value, the non-fungible token (NFT) of Dorsey’s original tweet—which was originally purchased for $2.9 million—has reportedly plummeted in value, with the buyer unable to resell it. The inability of the buyer to resell the digital asset highlights the shifting market perception of the platform’s early history and its legacy.

Why it matters

The platform’s 20-year milestone highlights a stark transition from a simple social experiment to a contentious, AI-integrated business currently struggling to maintain its market position against emerging rivals.
