Facebook is a social-network service website launched on February 4, , by Mark Zuckerberg. The following is a list of software and technology features that can be found on the Facebook website and mobile app and are available to users of the social media site. The news feed is the primary system through which users are exposed to content posted on the network. Using a secret method initially known as EdgeRank , Facebook selects a handful of updates to actually show users every time they visit their feed, out of an average of updates they can potentially receive. Originally, when users logged into Facebook, they were presented with a customizable version of their own profile. The new layout, by contrast, created an alternative home page in which users saw a constantly updated list of their friends' Facebook activity. News Feed highlights information that includes profile changes, upcoming events, and birthdays, among other updates. This has enabled spammers and other users to manipulate these features by creating illegitimate events or posting fake birthdays to attract attention to their profile or cause. News Feed also shows conversations taking place between the walls of a user's friends. An integral part of the News Feed interface is the Mini Feed, a news stream on the user's profile page that shows updates about that user.

Meta Platforms Inc. These stem partly from the company's revenue model that involves selling information collected about its users for many things including advertisement targeting. These issues and others are further described including user data concerns, vulnerabilities in the company's platform, investigations by pressure groups and government agencies, and even issues with students. In , the Electronic Frontier Foundation identified two personal information aggregation techniques called "connections" and "instant personalization". They demonstrated that anyone could get access to information saved to a Facebook profile, even if the information was not intended to be made public. Facebook treats such relationships as public information, and the user's identity may be displayed on the Facebook page of the product or service.

Amazingly, the idea for the website, now the world's most popular social networking page, was inspired by a botched effort to get internet users to rate one another's photos. In , Zuckerberg, a second-year student at Harvard, wrote the software for a website called Facemash. He put his computer science skills to questionable use by hacking into Harvard's security network, where he copied the student ID images used by the dormitories and used them to populate his new website. Website visitors could use Zuckerberg's site to compare two student photos side-by-side and determine who was "hot" and who was "not. Facemash opened on October 28, —and closed a few days later, after it was shut down by Harvard execs. In the aftermath, Zuckerberg faced serious charges of breach of security, violating copyrights, and violating individual privacy. Though he faced expulsion from Harvard for his actions, all charges against him were eventually dropped. On February 4, , Zuckerberg launched a new website called TheFacebook. He named the site after the directories that were handed out to university students to help them to get to know one another better. Six days later, he got into trouble again when Harvard seniors Cameron Winklevoss, Tyler Winklevoss, and Divya Narendra accused him of stealing their ideas for an intended social networking website called HarvardConnection.
