Twitter owner Elon Musk has said that the social media company will soon change its logo, getting rid of the blue bird that has long been its signature and replacing it with an X.

"And soon we will say goodbye to the Twitter brand and, gradually, to all birds," said the South African in a post on the social network.

About six months after acquiring Twitter for 44 billion dollars, Musk merged the company into an entity called X Corp, stating that Twitter is an accelerator for building an app for everything called X.

"If a good enough X logo comes out tonight, we'll be live around the world tomorrow," Musk wrote on Twitter on Saturday, quoted by bloomberg.

According to Reuters, the move, which was not evident on the site on Sunday evening, followed Musk's recent admission that advertising revenues are still almost half of what they were before. And Twitter's cash flow has been negative as a result of this and its heavy debt.

Musk polled his millions of followers to see if they would be in favor of changing the site's color scheme from blue to black. He posted a photo of an X modeled against a black background with an outer space theme.

Late on Sunday afternoon, Twitter's new CEO, Linda Yaccarino, tweeted: "It's an exceptionally rare thing - in life or in business - to get a second chance to make another big impression. Twitter made a big impression and changed the way we communicate. Now, X is going further, transforming the global town square."
