For almost two decades, Facebook's name has been virtually synonymous with social media. That might not be so good for the tech behemoth anymore.

Facebook is changing its corporate name to Meta, CEO Mark Zuckerberg confirmed on Thursday. The move comes more than a week after The Verge reported on a potential rebranding that reflects the company's increased focus on building a virtual world, known as a metaverse. The change also means that the company's various social media apps, including Facebook, Instagram and WhatsApp, will become subsidiaries.

Zuckerberg and Facebook are both facing more scrutiny than ever before over the company's spread of misinformation and hate speech, and its potential to be harmful for teenagers and children. And Facebook wouldn't be the first business to change its name or rebrand in a time of crisis.

Sometimes, it works. Sometimes it doesn't. These seven companies are proof of both:

Google becomes Alphabet

If Facebook's rebranding sounds familiar, it's because Google did something very similar in 2015, forming its parent company Alphabet.

Google's public rationale was to help emphasize Google's non-search business interests, like artificial intelligence, autonomous cars and venture capital investing. But at the time, Google was also under heightened scrutiny from government regulators, including antitrust inquiries over concerns that the company's business stifled competition.

The rebrand likely did little to shift public opinion: The company is still often referred to as Google, and Alphabet still faces antitrust scrutiny today. But from a financial standpoint, it's hard to call it a flop. Alphabet's stock price has nearly quintupled since the change, and the company now boasts a market value of $1.9 trillion.

Plus, a fun fact: This wasn't Google's first rebrand. Co-founders Larry Page and Sergey Brin changed the company's name to Google in 1998, after originally calling it BackRub.

Apple's small but significant name change

Even tiny changes can have huge ramifications.

In 2007, Apple Computer dropped the second word from its name — the same year as it released the first iPhone. At the time, co-founder Steve Jobs explained that Apple had evolved beyond being just a computer company. The name change was a reflection of Apple's increased focus on its other product lines.

Since the name change and iPhone launch, Apple's valuation has soared. Its stock price has increased by almost 1,200% in the past decade, giving Apple a valuation of more than $2.4 trillion — and the iPhone is the company's best-selling device.

In changing its name, Apple altered its identity while making a big bet on the future. That's essentially what Facebook is hoping to do now.

Dunkin' drops Donuts

In 2018, Dunkin' Donuts announced a similar move, dropping the word "Donuts" from its branding. The goal was to emphasize its menu of drink and savory food options, in the face of increased competition from chains like Starbucks.

At the time, the company said, customers reacted positively to the shortened name. Last year, though, its sales dipped as the coronavirus pandemic hit and foot traffic disappeared. And in October 2020, Dunkin' and sister brand Baskin-Robbins were acquired by Inspire Brands, which owns Arby's and Buffalo Wild Wings, for $11.3 billion.

KFC: Forget 'Fried'

Kentucky Fried Chicken similarly shortened its name to KFC in 1991. On the one hand, it wasn't much of a change: People had been calling the brand "KFC" for years.

But KFC executives admitted that they wanted to cultivate a healthier and more "contemporary" image for the company. Kyle Craig, the then-president of KFC U.S., put it this way: "Fried is not a contemporary image."

The change certainly didn't scare away any customers. Today, KFC is one of the world's largest fast-food chains. It's owned by Yum! Brands, which also owns Pizza Hut and Taco Bell, and its annual revenue grew to more than $26.2 billion last year, up from roughly $6 billion in 1991.

Philip Morris goes up in smoke

In 2001, Philip Morris, the manufacturer behind iconic cigarette brand Marlboro, changed the name of its parent company to the Altria Group.

The move came three years after Philip Morris and other big tobacco companies reached a $200 billion settlement with the U.S. government, over health costs related to smoking. Company executives admitted that the name change represented something of a clean slate for the company and its other holdings, which at the time included majority stakes in Kraft Foods and Miller Brewing.

Results have been mixed. Altria eventually spun off Miller and Kraft in separate deals. It still owns Marlboro producer Philip Morris USA, along with stakes in beverage company ABInBev, cannabis company Cronos Group and e-cigarette startup Juul.

In 2008, the company was dropped from the Dow Jones Industrial Average. Its stock price has dipped by more than 24% over the past five years, leading to its current market valuation of $89 billion.

Weight Watchers becomes an acronym

In 2018, a company once synonymous with shedding pounds changed its image to reflect changing attitudes toward weight loss and health.

Weight Watchers' membership declined in the mid-2010s, as more people decided they wanted to eat healthier without focusing specifically on losing weight. So the company rebranded as WW International, aiming to become more of a lifestyle and wellness brand.

The results have also been mixed. The company ended 2020 with 4.4 million subscribers, an all-time high. But WW's revenue and profit dipped last year, and its stock price is down to $18.34 per share, as of Thursday afternoon — compared to more than $66 per share when the rebrand was announced.

WWF goes down for the count

Sometimes, a rebrand is legally mandated. In 2002, the Worldwide Wrestling Foundation changed its name to World Wrestling Entertainment, following a years-long legal battle with the conservation group World Wildlife Fund.

Despite losing that battle, the WWE put a positive spin on the rebrand, saying that the change allowed the company to "emphasize the 'E' for entertainment."

Since then, the WWE has only grown: Despite the challenge of hosting live events during a pandemic, the company reported a record revenue of nearly $1 billion last year, due to lucrative media rights deals and international expansion.
