Twitter on Monday officially replaced its signature blue bird logo with a white X on a black background as part of a rebranding effort.
Twitter owner Elon Musk tweeted an image of the new X branding beamed onto the side of the social media company's headquarters in San Francisco, saying: "X.com now points to Twitter.com."
"X is here! Let's do this," Twitter's CEO Linda Yaccarino tweeted.
On late Saturday, Musk invited his followers to suggest an X logo and on Sunday chose one of the designs.
