The change, which was not evident on the website on Sunday afternoon, followed Musk’s recent admission that advertising revenue remains nearly half of what it once was. And Twitter’s cash flow has been negative as a result of that and its heavy debt load.

“Interim X logo goes live later today,” Musk said on Twitter adding that “X.com” would now redirect to Twitter’s website. Musk’s X Corp owns Twitter.

The billionaire said in a Sunday post he wanted to change Twitter’s logo and polled his millions of followers whether they would favor changing the site’s color scheme from blue to black. He posted a picture of a stylised X against a black outer space-themed background.

“And soon we shall bid adieu to the twitter brand and, gradually, all the birds”, he said. The company said it would be commenting on the changes later.

Under Musk’s tumultuous tenure since he bought Twitter in October, the company has changed its business name to X Corp, reflecting the billionaire’s vision to create a “super app” like China’s WeChat.

In April, Twitter’s legacy blue bird logo was temporarily replaced by Dogecoin’s Shiba Inu dog, helping drive a surge in the cryptocurrency’s market value.

The company came under widespread criticism from users and marketing professionals when Musk announced early this month that Twitter would limit how many tweets per day various accounts can read.

The daily limits helped Meta Platforms-owned rival service Threads, which crossed 100 million sign-ups within five days of its July 5 launch.
