X Logo Officially Replaces Twitter’s Popular Bird on Mobile Application

X, earlier known as Twitter, has officially retired its popular blue and white bird logo.

The icon on the mobile application changed to an “X” in the latest phase of a sweeping rebrand Elon Musk announced at the start of July. The company earlier introduced the logo on the website and launched the domain X.com, though Twitter.com is still live.

Musk wrote in a post Sunday, “The company would soon bid adieu to the Twitter brand and, gradually, all the birds.” The transition to X reflects Musk’s vision to turn the platform into an ‘everything app’.

The Tesla CEO Elon Musk has long been fascinated with the letter ‘x’.

Musk recently hired former NBCUniversal advertising executive Linda Yaccarino as CEO, seen as a move to help reassure advertisers.

In an email to employees, Linda Yaccarino wrote, “X will develop experiences in video, audio, messaging, banking, and payments that will delight users. We plan to work across every team to keep the entire community up to date.”

Yaccarino wrote in a post about the mobile application’s logo change, “Time to update.”
