Facebook is a social networking service and platform created in 2004 by Mark Zuckerberg, along with fellow Harvard University students Eduardo Saverin, Dustin Moskovitz, Andrew McCollum, and Chris Hughes. Initially exclusive to Harvard students, it expanded to other universities and eventually to anyone over 13 years old. It is now owned by Meta Platforms. Facebook can be accessed on devices with internet connectivity, such as computers, tablets, and smartphones.
Key features include user profiles where individuals can share personal updates, photos, and multimedia content with friends or the public, depending on privacy settings. Users can communicate directly via Messenger, join groups, and receive notifications about friends' activities. The "News Feed" displays content and updates, using an algorithm to prioritize what users see. Facebook is available in 112 languages. Access to Facebook is free, with revenue primarily generated through targeted advertising. The average cost per click for Facebook ads is about $0.70 for traffic campaigns and $1.92 for leads campaigns, with the average cost per lead around $27.66. Facebook provides tools for content creators, including Creator Studio, to manage and monetize their content. New features powered by Meta AI allow users to animate their profile pictures and restyle photos and memories.
