Facebook, Inc., is an American multinational conglomerate based in Menlo Park, California. It was founded by Mark Zuckerberg, along with his fellow roommates and students at Harvard College, originally as TheFacebook.com—today's Facebook, a popular global social networking service. It is one of the world's most valuable companies. It is considered one of the Big Five companies in U.S. information technology, with Google, Apple, Microsoft and Amazon.

Facebook offers other products and services beyond its social networking platform, including Facebook Messenger, Facebook Watch, and Facebook Portal. It also has acquired Instagram, WhatsApp, Oculus, Giphy and Mapillary, and has a 9.99% stake in Jio Platforms.

Facebook filed for an initial public offering (IPO) on February 1, 2012. The preliminary prospectus stated that the company sought to raise $5 billion, that the company had 845 million active monthly users, and that its website featured 2.7 billion daily likes and comments. After the IPO, Zuckerberg would retain a 22% ownership share in Facebook and would own 57% of the voting shares.

In May 2019, Facebook founded Libra Networks, reportedly to develop their own stablecoin cryptocurrency. In recent developments it has been reported that Libra is being supported by financial companies like Visa, Mastercard, PayPal and Uber. The consortium of companies is expected to pool in $10 million each to fund the launch of the cryptocurrency coin named Libra. Depending on when it receives approval from the Swiss Financial Market Supervisory authority to operate as a payments service, the Libra Association plans to launch a limited format cryptocurrency in 2021.
