usage note for Facebook
The official trademarked name of the social-media platform and website is spelled “facebook,” all lowercase letters. Formal writing style—as exemplified by most news and book publishers—is to treat such names as regular proper nouns, in this case “Facebook,” using an initial capital letter. 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.
