Once clicked by a user, the designated content appears in the News Feeds of that user's friends, [] [] and the button also displays the number of other users who have liked the content, including a full or partial list of those users. Facebook Messenger is an instant messaging service and software application. Originally developed as Facebook Chat in , [] the company revamped its messaging service in , [] and subsequently released standalone iOS and Android apps in August Facebook Messenger lets Facebook users send messages to each other.

Complementing regular conversations, Messenger lets users make voice calls [] and video calls [] both in one-to-one interactions [] and in group conversations. In March , Facebook announced that it would start letting businesses and users interact through Messenger with features such as tracking purchases and receiving notifications, and interacting with customer service representatives. It also announced that third-party developers could integrate their apps into Messenger, letting users enter an app while inside Messenger and optionally share details from the app into a chat.

On September 14, , Facebook added the ability for users to provide a "Subscribe" button on their page, which allows users to subscribe to public postings by the user without needing to add him or her as a friend.

The media often compares Facebook to Myspace , but one significant difference between the two Web sites is the level of customization. They include the Wall , a space on every user's profile page that allows friends to post messages for the user to see; [] Pokes , which allows users to send a virtual "poke" to each other a notification then tells a user that he or she has been poked ; [] Photos , that allows users to upload albums and photos; [] and Status , which allows users to inform their friends of their whereabouts and actions.

Depending on privacy settings, anyone who can see a user's profile can also view that user's Wall. In July , Facebook began allowing users to post attachments to the Wall, whereas the Wall was previously limited to textual content only. Facebook uses advertising in the form of banner ads, referral marketing, and games.

Myspace, on the other hand, uses Google and AdSense. MySpace, initially, was much more popular with high school students, while Facebook was more popular among college students. A study by the American firm Nielsen Claritas showed that Facebook users are more inclined to use other professional networking sites, such as LinkedIn , than Myspace users. Facebook enables users to choose their own privacy settings and choose who can see specific parts of their profile.

Users can control who sees other information they have shared, as well as who can find them in searches, through their privacy settings. Its purpose was to allow targeted advertisements and allowing users to share their activities with their friends. In , Facebook's security team began expanding its efforts to reduce the risks to users' privacy, [] but privacy concerns remain.

On November 29, , Facebook settled Federal Trade Commission charges that it deceived consumers by failing to keep privacy promises. In April , in the wake of the Cambridge Analytica data breach scandal , and refuting a report to the contrary by Reuters , Mark Zuckerberg announced that Facebook would implement additional privacy "controls and settings" worldwide. In the aftermath of the breach, Facebook withdrew its opposition to the California Consumer Privacy Act.

According to the Committee Facebook "simply formally dropped their participation in the 'no' campaign. Facebook's Whitehat page for security researchers says: Facebook started paying researchers who find and report security bugs by issuing them custom branded "White Hat" debit cards that can be reloaded with funds each time the researchers discover new flaws.

They can show up at a conference and show this card and say 'I did special work for Facebook. India, which has the second largest number of bug hunters in the world, [] tops the Facebook Bug Bounty Program with the largest number of valid bugs. Stan Schroeder of Mashable questioned how the measurement of "active" was made, though acknowledging that "it probably means that users who've just created an account which sits idle for a long period of time aren't included".

Mark Zuckerberg announced to the media at the start of October that Facebook had passed the monthly active users mark of one billion. Early in , it was reported that teenagers preferred competing web sites such as Instagram and Snapchat. The estimated number of teens leaving Facebook was a million per year.

In November , after skepticism about the accuracy of its "monthly active users" measurement, Facebook changed its definition of an "active user", now defining it as a logged-in member who visits the Facebook site through the web browser or mobile app, or uses the Facebook Messenger app, in the last 30 days of the date of measurement. This excludes the use of third-party services with Facebook integration, which was previously counted. Active users of Facebook increased from just a million in to over million in Population pyramid of Facebook users by age as of January 1, [].

According to analytics firm comScore , Facebook is the leading social networking site based on monthly unique visitors, having overtaken main competitor MySpace in April Facebook is the most popular social networking site in several English-speaking countries , including Canada, [] the United Kingdom, [] and the United States.

The reasons why Facebook scored so poorly include privacy problems, frequent changes to the website's interface, the results returned by the News Feed, and spam. In December , the Supreme Court of the Australian Capital Territory ruled that Facebook is a valid protocol to serve court notices to defendants. It is believed to be the world's first legal judgement that defines a summons posted on Facebook as legally binding.

By , the use of Facebook had already become so ubiquitous that the generic verb "facebooking" had come into use to describe the process of browsing others' profiles or updating one's own. Facebook's market dominance has led to international media coverage and significant reporting of its shortcomings. Notable issues include Internet privacy , such as its widespread use of a "like" button on third-party websites tracking users , [] [] possible indefinite records of user information, [] automatic facial recognition software, [] [] and its role in the workplace, including employer-employee account disclosure.

The World's Biggest Waste of Time? The use of Facebook can have psychological effects, including feelings of jealousy [] [] and stress, [] [] a lack of attention, [] and social media addiction, in some cases comparable to drug addiction.

In an interview with The New Yorker , antitrust regulator Margrethe Vestager stated that Facebook's terms of use that concern private data were "unbalanced".

She noted that users accept terms they would never accept in a more traditional environment, such as "if a brick-and-mortar business asked to copy all your photographs for its unlimited, unspecified uses". Facebook's company tactics have also received prominent coverage, including electricity usage, [] tax avoidance, [] real-name user requirement policies, [] censorship, [] [] and its involvement in the United States PRISM surveillance program.

Due to allowing users to publish material by themselves, Facebook has come under scrutiny for the amount of freedom it gives users, including copyright and intellectual property infringement, [] hate speech , [] [] incitement of rape [] and terrorism, [] [] fake news , [] [] [] and crimes, murders and violent incidents live-streamed through its Facebook Live functionality.

Facebook worked on special censorship software so it could potentially accommodate censorship demands in Communist -controlled China. The company has also been subject to multiple litigation cases over the years, [] [] [] [] with its most prominent case concerning allegations that CEO Mark Zuckerberg broke an oral contract with Cameron Winklevoss , Tyler Winklevoss , and Divya Narendra to build the then-named "HarvardConnection" social network in , instead allegedly opting to steal the idea and code to launch Facebook months before HarvardConnection began.

On November 5, , the Paradise Papers , a set of confidential electronic documents relating to offshore investment , revealed that Russian state organizations with ties to Vladimir Putin pursued between and large investments in Facebook and Twitter via an intermediary—Russian-American entrepreneur Yuri Milner , who befriended Facebook founder Mark Zuckerberg [] and invested in the company co-founded by Jared Kushner , President Donald Trump 's son-in-law.

On March 6, , BlackBerry sued Facebook and its Instagram and WhatsApp subdivision for ripping off key features of its messaging app. On June 7, , chief privacy officer Erin Egan noted that a software bug had resulted in about 14 million Facebook users having their default sharing setting for all new posts set to "public". Facebook issued a notification to users which were exposed to this issue. A Facebook spokesperson said the notification is the start of new proactive and transparent way for the company to handle issues going forward.

This includes data that Facebook collects on non-users that may be collected by the Facebook analytics Pixel or location data from a mobile phone.

In March , whistleblowers revealed that personal information from over 87 million Facebook users was sold to Cambridge Analytica , a political data analysis firm that had worked for Donald Trump 's presidential campaign.

The data was collected using an app created by Global Science Research. However, with increasing scrutiny, Facebook issued a statement expressing alarm and suspended Cambridge Analytica, while review of documents and interviews with former Facebook employees suggested that Cambridge Analytica was still in possession of the data. According to The Guardian reporter Carole Cadwalladr who broke the story, both Facebook and Cambridge Analytica threatened to sue the newspaper if it published the story and continually tried to prevent its publication.

After the story was published anyway, Facebook claimed that it had been "lied to". Cadwalladr said that Facebook was trying to shift the blame onto a third party. Nick Thompson of Wired and CBS News pointed out that Cambridge Analytica obtained all the personal data without having to "breach" Facebook, and that "It didn't work because somebody hacked in and broke stuff, it worked because Facebook has built the craziest most invasive advertising model in the history of the world and someone took advantage of it.

You may have heard about a quiz app built by a university researcher that leaked Facebook data of millions of people in This was a breach of trust, and I'm sorry we didn't do more at the time. We're now taking steps to make sure this doesn't happen again. We've already stopped apps like this from getting so much information.

Now we're limiting the data apps get when you sign in using Facebook. We're also investigating every single app that had access to large amounts of data before we fixed this. We expect there are others. And when we find them, we will ban them and tell everyone affected. Finally, we'll remind you which apps you've give access to your information — so you can shut off the ones you don't want anymore. On March 26, the Federal Trade Commission opened an investigation into Facebook regarding the use of its data by Cambridge Analytica, causing stocks to temporarily drop by more than 5 percent.

In Android platform, It was reported that Facebook app has been gathering Android users data for years. Unlike Android, Apple limited the privilege of the apps who try to gather personal information from the iOS devices.

In May , several Android users in California filed a class action lawsuit against Facebook for invading their privacy by unauthorized access in storing personal contact data especially call and text message history without users' consent. In early March , The Observer reported that a "political consultancy" known as Cambridge Analytica had been provided access to the personal data of about 50 million Americans by Facebook.

However, another article was published on April 4 by Wired that reports a statement made by Facebook regarding the number of people affected. When users downloaded this app — called "thisisyourdigitallife" — information regarding the users' preferred Facebook content as well as their "home town" could then be accessed by the app.

This was than used to acquire similar information of the user's contacts and continued to affect approximately 50 million people in total. This backlash has also taken the form of demands for legal accountability, including the opening of an investigation into the company by the U.

Thus, mobile phone manufactures and carriers have been beneficiaries of Facebook's spillover effect. Three distinct areas have been found to add the most economic impact: Facebook began to reduce its carbon impact after being publicly criticised by Greenpeace for its long-term reliance on coal power and consequently high carbon footprint. Facebook provides a development platform for many social gaming , communication, feedback, review, and other applications related to online activities.

Facebook has been successful and more socially impactful than many other social media sites. David Kirkpatrick, technology journalist and author of The Facebook Effect , believes that Facebook is structured in a way that is not easily replaceable.

The Russians took advantage of Facebook's ability to simultaneously send contrary messages to different groups of users based on their political and demographic characteristics and also sought to sow discord among religious groups. Other ads highlighted support for Democrat Hillary Clinton among Muslim women.

The ads suggest that Russian operatives worked off of evolving lists of racial, religious, political and economic themes. They used these to create pages, write posts and craft ads that would appear in users' news feeds—with the apparent goal of appealing to one audience and alienating another. On March 17, , The New York Times and The Observer of London reported the Facebook and Cambridge Analytica data breach in which Cambridge Analytica collected personal information from Facebook users as a basis of crafting political campaigns for whomever purchased their services.
