Elon Musk reportedly told Twitter employees late Saturday night that he’d just sent his last email from a Twitter address, implying the platform’s touted rebranding to “X” might be happening sooner rather than later. He reportedly signed the email with a salute emoji. “And soon we shall bid adieu to the twitter brand and, gradually, all the birds,” Musk tweeted early Sunday morning, adding in a subsequent tweet that “if a good enough X logo is posted tonight, we’ll make go live [sic] worldwide tomorrow.” He spent the remaining early hours of Sunday morning teasing the logo change, even sharing a three-second animation of the Twitter logo fading out to an “X.”
