Facebook is a social platform that enables people to share updates, photos, and videos while connecting with friends, family, and communities. Since its public launch in 2004, it has evolved into a multibillion-user service that hosts personal profiles, groups, pages, and marketplace commerce. This profile explains how Facebook works, how it has changed over time, and what users commonly seek, with an emphasis on verifiable details and durable explanations rather than time-sensitive news.
What Is Facebook and How It Works
Facebook is a social networking service that lets users create a public profile with basic information, photos, and contact details. People can add friends, join groups, follow pages, and interact with posts through likes, comments, and shares. The platform uses an algorithm to determine which content appears in News Feed, prioritizing content it predicts will drive engagement based on past behavior and stated preferences. Users can adjust who sees each post, control notifications, and manage activity through privacy and preferences settings.
Key Features and Core Products
Facebook’s core product is the main social network, accessible via web and mobile apps. It includes features such as the News Feed, Friends and Followers lists, Groups, Pages, Events, and Marketplace. Messenger provides direct messaging and calling, while other products such as Instagram and WhatsApp are now part of the same underlying infrastructure, though they operate with distinct brand experiences. Many of these features are also accessible via the standalone Messenger app, and business tools like Facebook Ads allow advertisers to target audiences based on demographics, interest, and behavior signals.
Main Social Features
- News Feed and Timeline: Personalized content streams and profile history.
- Groups and Pages: Communities and public-facing profiles for organizations.
- Events and Marketplace: Event invitations and buying/selling local items.
- Messaging: One-to-one and group conversations, voice and video calls.

Facebook launched in February 2004 as a Harvard-only service before expanding to other colleges, then to high schools, and eventually to everyone aged 13 and older with verified accounts.

Below are selected verified milestones that illustrate its growth and product evolution.

Business Model and Revenue
Facebook primarily generates revenue through advertising on its services. Advertisers can target audiences by demographics, interests, behaviors, and custom audiences, paying based on impressions or clicks. In addition to ads, the company earns from transaction fees in Marketplace and from premium features such as boosted posts for Pages. Financial results and detailed revenue breakdowns are typically reported quarterly and are available in official filings and investor reports.
Community Standards and Policies
Facebook enforces community standards that prohibit harassment, hate speech, violence, and spam. Content moderation combines automated systems and human reviewers to detect and remove violating material. Users can report posts, appeals decisions, and control who can contact or see their content. Policies are periodically updated in response to regulatory input and evolving user expectations, with summaries and detailed guidelines published in its official resources.
User Privacy and Data Controls
Privacy settings allow users to manage who sees their posts, who can send messages or friend requests, and what information appears on their timeline. Users can review activity logs, download their data, and adjust ad preferences. The platform has faced scrutiny over data usage, leading to product changes and greater transparency tools. For accurate, current instructions, users should consult the official Help Center, as features and options may change over time.
