SAN FRANCISCO — Facebook rose to prominence over the past two decades with some of the world’s most recognizable branding: a big blue-and-white letter F.

No longer. On Thursday, the social networking giant took an unmistakable step toward an overhaul, de-emphasizing Facebook’s name and rebranding itself as Meta. The change was accompanied by a new corporate logo designed like an infinity-shaped symbol that was slightly askew. Facebook and its other apps, such as Instagram and WhatsApp, will remain but under the Meta umbrella.

The move punctuates how Mark Zuckerberg, the chief executive, plans to refocus his Silicon Valley company on what he sees as the next digital frontier, which is the unification of disparate digital worlds into something called the metaverse. At the same time, renaming Facebook may help distance the company from the social networking controversies it is facing, including how it is used to spread hate speech and misinformation.

“I’ve been thinking a lot about our identity” with this new chapter, Mr. Zuckerberg said, speaking at a virtual event on Thursday to showcase Facebook’s technological bets on the future. “Over time, I hope we’re seen as a metaverse company.”
