Spelling
The official trademarked name of the social media platform and website is now styled in all capital letters “FACEBOOK,” though prior to 2020 the trademarked style was “facebook,” in all lowercase letters. Formal writing—as exemplified by most news and book publishers—treats such names as regular proper nouns, in this case “Facebook,” using an initial capital letter, but not all caps. However, when a trade name begins with a lowercase letter followed by an uppercase one, such as eBay or iPad, this spelling is retained, even at the beginning of a sentence.
Etymology
Origin of Facebook
First recorded in 2000–05; from facebook, a college student directory with personal photos and basic information
