Twitter has removed the iconic bird logo and adopted ‘X’ as its official logo. This move comes after Elon Musk announced the change over the weekend. The change is already live on the website.

Notably, Musk tweeted that x.com now also redirects to twitter.com. In the post, Musk also called this an “interim” logo, so we might see another logo change in the future.
