On 23 July 2023, Elon Musk announced that Twitter would be renamed X. The iconic blue bird logo was removed from the San Francisco headquarters and from the app, replaced by a stylised X. The change happened over a weekend, with little external research or staged transition. Musk framed it as the first step toward turning the platform into an 'everything app' modelled on WeChat.
The Twitter name had been established for 17 years and the word 'tweet' had entered common language. Brand Finance valued the Twitter brand at roughly $5.7 billion before the takeover and estimated it fell to $3.9 billion in 2023 and lower still in 2024 after the rebrand. The firm attributed much of the decline to the loss of name recognition, trust and advertiser confidence rather than to market conditions alone.
Advertisers and users continued to refer to the platform as Twitter, and media outlets kept using 'formerly Twitter' in headlines. The rebrand also created trademark risks because multiple companies, including Meta and Microsoft, held existing X marks. The decision became a widely cited example of discarding a category-defining brand in pursuit of a founder's abstract vision.
Musk replaced the 17-year-old Twitter name and blue bird with X over a weekend, and Brand Finance estimated the brand's value fell from $5.7 billion to $3.9 billion.
The Twitter name and bird were globally recognised; replacing them removed decades of built-up brand equity without a transition plan
The rebrand was executed over a weekend, leaving no time for user, advertiser or legal-system adjustment
The new name X is generic and hard to trademark, search for, or distinguish in conversation
The change discarded a verb ('tweet') that had become part of everyday language, a rare and valuable linguistic asset
A brand name that has become a verb is worth more than the founder's preference. Rebranding should be staged, researched and legally cleared; doing it overnight turns equity into confusion.
X continued to operate under the new name, but Brand Finance reported further declines in brand value through 2024. The platform's advertising revenue fell sharply, and many users and publications still referred to it as Twitter. The case is now used in branding courses as a cautionary example of discarding a mature, category-defining identity.
