Elon Musk, the CEO of Tesla, has revealed a fresh and minimalist "X" logo to replace Twitter's iconic blue bird, signaling a significant rebranding of the social media platform he acquired for $44 billion last year.

The letter "X" began appearing on Twitter's desktop version on Monday, while the bird still dominated the smartphone app.

However, the removal of the bird and logo at Twitter's San Francisco headquarters faced obstacles when police halted the process due to a lack of proper permits and safety measures. The X.com web domain now redirects to Twitter.com, further solidifying Musk's rebranding efforts.

Musk's fascination with the letter "X" is evident, as he has renamed Twitter's corporate name to X Corp. and plans to call tweets "Xs" after the rebranding. The billionaire's Twitter acquisition and subsequent changes aim to create an "everything app," akin to China's WeChat, integrating video chats, messaging, streaming, and payments. He has already shifted Twitter's focus to paid subscriptions, but some of his grand policy pronouncements remain unfulfilled.

Despite the excitement of Musk's supporters, ad industry analysts express skepticism about X's prospects. While Linda Yaccarino, the CEO appointed by Musk, hailed X as the future state of unlimited interactivity, analysts believe Twitter's established brand equity has already waned.

The rebranding could further alienate users and advertisers, considering Musk's previous modifications, such as limiting the number of tweets users can read and introducing a subscription service.

Musk's vision for an "everything app" and the success of the rebranding will dictate whether advertisers will return to the platform.

However, some experts argue that advertisers care more about the app's effectiveness than its name change. Whether Musk's strategies prove fruitful and create a global marketplace for ideas, goods, services, and opportunities remains to be seen.

For now, Musk's "X" logo ushers in a new era for Twitter, leaving behind the recognizable blue bird that has represented the platform for over a decade.
