Twitter launched its new logo on Monday, replacing the blue bird with a white X on a black background as the company moves toward rebranding as X.

The social media network’s website showed the company’s new logo, but its URL was still showing as twitter.com and the blue “Tweet” button was visible.

Some users saw a blue version of the X logo, suggesting the rollout was not yet finalised.

Owner Elon Musk and the company’s CEO had revealed the new logo on Sunday, saying the company would be renamed X and move later into payments, banking and commerce.

Founded in 2006, Twitter takes its name from the sound of birds chattering, and it has used avian branding since its early days, when the company bought a stock symbol of a light blue bird for $15, according to the design website Creative Bloq.

Tweeting a picture of the company’s new logo Sunday night, Twitter chief executive Linda Yaccarino said “X is here! Let’s do this.”

Also late on Sunday, Musk changed his profile picture to the company’s new logo, which he described as “minimalist art deco”, and updated his Twitter bio to “X.com”, which now redirects to twitter.com.

He also tweeted that under the site’s new identity, a post would be called “an X”.

Musk had already named Twitter’s parent company the X Corporation, and has said his takeover of the social media giant was “an accelerant to creating X, the everything app” — a reference to the X.com company he founded in 1999, a later version of which went on to become online payments giant PayPal.

Such an app could still function as a social media platform, and also include messaging and mobile payments.

“Powered by AI, X will connect us in ways we’re just beginning to imagine,” Yaccarino tweeted on Sunday.

Yaccarino, a former advertising sales executive at NBC Universal who Musk hired last month to be Twitter’s CEO, said the social media platform was on the cusp of broadening its scope.

“X is the future state of unlimited interactivity — centred in audio, video, messaging, payments/banking — creating a global marketplace for ideas, goods, services, and opportunities,” Yaccarino tweeted.

New revenue streams

Since Musk bought Twitter for $44 billion last October, the platform’s advertising business has partially collapsed as marketers soured on Musk’s management style and mass firings at the company that gutted content moderation.

In response, the billionaire SpaceX boss has moved toward introducing payments and commerce through the platform in a search for new revenue.

The platform is thought to have around 200 million daily active users, but it has suffered repeated technical failures since Musk sacked much of its staff.

Many users and advertisers alike have responded adversely to the social media site’s new charges for previously free services, its changes to content moderation and the return of previously banned right-wing accounts.

Musk said this month that Twitter had lost roughly half of its advertising revenue since he took control.

Facebook parent Meta also this month launched its text-based platform, called Threads, which has up to 150 million users, according to some estimates.

But the amount of time users spend on the rival app has plummeted in the weeks since its launch, according to data from market analysis firm Sensor Tower.
