Twitter’s public rebrand to X began on July 24, 2023. X’s own August 2023 product timeline records that date as the introduction of X to the world.
Separate the different changes
| Change | What it means |
|---|---|
| Corporate identity | The legal company name and corporate arrangements are separate from the user-facing logo change |
| July 24, 2023 public rebrand | The date X’s product timeline identifies for introducing X |
| Later interface and domain changes | Labels, help pages, links and app branding did not all change in one moment |
The linked product timeline supports the public date; it is not documentation of the exact corporate-merger or domain-migration date.
Why both names remain in use
People still use “Twitter,” “tweet” and “retweet,” especially when discussing historical material. Current interfaces often use X, post and repost. The naming change alone does not identify a new account or prove that a source post was changed. Claims about the rebrand’s success or motive need separate evidence.
Keep original URLs in historical records
For an old post or archive, retain the original URL, post ID and capture date. Check any redirect when opening it now; do not promise that every historical link or deleted post remains available. Use Twitter/X terminology where it helps distinguish the historical interface from the current service. A rebrand is not a guarantee of data preservation.
