Twitter today officially ditched its iconic blue bird logo for a simple white X on a black background. The change is part of a wider rebranding effort under Elon Musk's ownership of the platform.
Early today, Mr Musk tweeted an image of the X branding beamed across Twitter's headquarters in San Francisco.
"Our headquarters tonight," he tweeted.
The SpaceX and Tesla chief's fascination with the letter X goes back to the 1990s. In 1999, he launched the X.com domain, an online banking services platform that is a precursor to PayPal. In 2017, Mr Musk repurchased the X.com domain and it was kept as one of his unused assets until his big announcement on Twitter's future on Sunday.
Following the purchase, he tweeted that the domain carries a lot of "sentimental value" for him, possibly a homage to his early entrepreneurial days.
Mr Musk tweeted on Sunday that he was changing Twitter's logo to an "X" to "symbolize the imperfections in all of us that make us unique".
