"And soon we shall bid adieu to the Twitter brand and, gradually, all the birds," he tweeted just after midnight Sunday.

The new "X" logo was also announced Sunday, and the following day, it was formally changed on the social media platform.

The logo was also projected onto Twitter’s San Francisco headquarters.

Musk, who also owns SpaceX and Tesla, has said he hopes Twitter/X will exist as a global chat service that allows users to easily write messages, share videos and produce and market content. The app will also shift to better allow users to create content and personally profit through subscriptions.

The Tesla and SpaceX chief finalized his purchase of Twitter, Inc in October 2022 for roughly $44 billion.

"The bird is freed," Musk tweeted at the time.
