Twitter owner and Tesla CEO Elon Musk announced on Sunday that the iconic logo of the bluebird will now be replaced by "X". He tweeted, "And soon we shall bid adieu to the twitter brand and, gradually, all the birds."

Last night, he again wrote: "X.com now points to twitter.com. Interim X logo goes live today."

He also teased a short flickering video of the logo set against a dark background.

Musk had not long ago changed the name of Twitter's holding company to X Corp.

Back in 2017, Musk bought back X.com, expressing his long-standing fascination with the letter X. "Thanks PayPal for allowing me to buy back X.com! No plans right now, but it has great sentimental value to me," he tweeted.

Twitter and X Corp CEO Linda Yaccarino also seemed to be on board with the plan: "It’s an exceptionally rare thing – in life or in business – that you get a second chance to make another big impression. Twitter made one massive impression and changed the way we communicate. Now, X will go further, transforming the global town square."

However, this is not the first time Musk has experimented with the Twitter logo. In April, he caused a furore on the internet by temporarily changing the logo with Dogecoin's Shiba Inu dog.
