TwitterX

TwitterX is the social media platform that originated as Twitter, a microblogging service launched in 2006. It allows users to post short messages called tweets and to engage through replies, likes, retweets, and direct messages. After Elon Musk’s 2022 acquisition, the brand was reorganized under X, and in 2023 the public-facing name became X, with the logo and app icons adopting an X motif. The twitter.com domain continues to be used alongside X branding.

History: Twitter was founded in 2006 by Jack Dorsey, Noah Glass, Biz Stone, and Evan Williams. It expanded the character limit to 280 in 2017. In 2022, Musk acquired the company for about $44 billion. In 2023 the brand transitioned to X, with the corporate structure reorganized under X Corp, a part of X Holdings. The change affected branding across apps and messaging, while the underlying service remained the same.

Features and business model: Tweets remain the core post format; users can follow accounts, like, reply to, or quote posts, and save posts for later. The platform includes Spaces for live audio discussions and supports various media. Revenue comes from advertising and a paid subscription tier, known at different times as Twitter Blue and X Premium, which provides enhanced features. Developer access to the API has shifted toward paid plans and restricted access.

Reception and usage: The rebranding and policy updates have drawn a range of responses, including concerns about moderation, platform stability, and advertiser sentiment. The service remains widely used by individuals, journalists, brands, and public figures and is available on iOS, Android, and web, with a broad set of language options.
