An aerial view shows a newly constructed X sign on the roof of the headquarters of the social media platform previously known as Twitter, in San Francisco, on July 29, 2023. Elon Musk killed off the Twitter logo on July 24, 2023, replacing the world-recognized blue bird with a white X as the tycoon accelerates his efforts to transform the floundering social media giant. Musk and the company’s new chief executive Linda Yaccarino announced the rebranding on July 23, 2023, scrapping one of technology’s most iconic brands in the latest shock move since the tycoon took over Twitter nine months ago.
