Facebook Messenger (sometimes abbreviated as Messenger) is an instant messaging service and software application. Originally developed as Facebook Chat in 2008, the company revamped its messaging service in 2010, and subsequently released standalone iOS and Android apps in August 2011. Over the years, Facebook has released new apps on a variety of different operating systems, launched a dedicated website interface, and separated the messaging functionality from the main Facebook app, requiring users to download the standalone apps.
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. Its Android app has integrated support for SMS and "Chat Heads", which are round profile photo icons appearing on-screen regardless of what app is open, while both apps support multiple accounts, conversations with optional end-to-end encryption, and playing "Instant Games", which are select games built into Messenger. Some features, including sending money and requesting transportation, are limited to the United States. In 2017, Facebook has added "Messenger Day", a feature that lets users share photos and videos in a story-format with all their friends with the content disappearing after 24 hours; Reactions, which lets users tap and hold a message to add a reaction through an emoji; and Mentions, which lets users in group conversations type @ to give a particular user a notification.
In March 2015, 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. In April 2016, it introduced an API for developers to build chatbots into Messenger, for uses such as news publishers building bots to give users news through the service, and in April 2017, it enabled the M virtual assistant for users in the U.S., which scans chats for keywords and suggests relevant actions, such as its payments system for users mentioning money. Additionally, Facebook expanded the use of bots, incorporating group chatbots into Messenger as "Chat Extensions", adding a "Discovery" tab for finding bots, and enabling special, branded QR codes that, when scanned, take the user to a specific bot.
After being separated from the main Facebook app, Messenger had 600 million users in April 2015, growing to 900 million in June 2016, 1 billion in July 2016, and 1.2 billion in April 2017.

History
Following tests of a new instant messaging platform on Facebook in March 2008, the feature, then-titled "Facebook Chat", was gradually released to users in April 2008. Facebook revamped its messaging platform in November 2010, and subsequently acquired group messaging service Beluga in March 2011, which the company used to launch its standalone iOS and Android mobile apps on August 9, 2011. Facebook later launched a BlackBerry version in October 2011. An app for Windows Phone, though lacking features including voice messaging and chat heads, was released in March 2014. In April 2014, Facebook announced that the messaging feature would be removed from the main Facebook app and users will be required to download the separate Messenger app. An iPad-optimized version of the iOS app was released in July 2014. In April 2015, Facebook launched a website interface for Messenger. A Tizen app was released on July 13, 2015. In October 2016, Facebook released Facebook Messenger Lite, a stripped-down version of Messenger with a reduced feature set. The app is aimed primarily at old Android phones and regions where high-speed Internet is not widely available. Facebook Messenger Lite is only available in Kenya, Tunisia, Malaysia, Sri Lanka and Venezuela, and is set to come to other countries later. In April 2017, Facebook Messenger Lite was expanded to 132 more countries. In May 2017, Facebook revamped the design for Messenger on Android and iOS, bringing a new home screen with tabs and categorization of content and interactive media, red dots indicating new activity, and relocated sections.
Facebook announced a Messenger program for Windows 7 in a limited beta test in November 2011. The following month, Israeli blog TechIT leaked a download link for the program, with Facebook subsequently confirming and officially releasing the program. The program was eventually discontinued in March 2014. A Firefox web browser add-on was released in December 2012, but was also discontinued in March 2014.

Features
Accounts
In December 2012, Facebook announced that Android users could sign up to the app without a Facebook account, requiring only a name and phone number. In October 2013, Facebook made it possible for users to send messages to other users without the requirement of being friends, as long as the user has the phone number of the other user in their contact list.
Chat Heads
In April 2013, Facebook introduced a "Chat Heads" feature to its Messenger Android app, which displays a round icon with a contact's profile photo, appearing on the screen regardless of which app is open.
Money transfer
In March 2015, Facebook added a feature for U.S. users to send money to friends. In April 2017, the feature was expanded to support group payments.
Calls
In January 2013, Facebook added voice calling to Facebook Messenger users in Canada, later expanding the feature to users in the United States a few days later. In April 2015, Facebook introduced video calling in select countries. In April 2016, group voice calling was introduced, with a maximum number of 50 call participants. The following December, Facebook enabled group video calling for up to 50 people.
Location sharing
In June 2015, Facebook introduced a revamped location sharing. Users tap on a "Location" button and are then shown a map with the ability to pinpoint any location, even if the user themselves is not present at the place. In March 2017, it introduced live location sharing, letting users temporarily share their location with a friend or group of friends for one hour at a time.
Business interaction and third-party app integration
At the Facebook F8 conference on March 25, 2015, Facebook announced multiple significant changes to the Messenger platform. Messenger will start letting users interact with businesses, including track purchases and receive notifications, and have personal conversations with company customer service representatives. Users will also be able to open compatible third-party apps inside Messenger, such as a movie ticketing service or GIF generators, and then share those details with the other chat participants.
Transportation requests
In December 2015, Messenger integrated with Uber to let U.S. users request a car directly from the app. Support for Lyft was added in March 2016. Support for the UberPOOL carpooling service was introduced in July 2016.
SMS support
In 2012, Facebook implemented support for SMS texting within the Messenger Android app. However, the feature was dropped in 2013 due to "extensive reworking" of the app, with a Facebook product manager stating that the SMS feature "just didn't take off". SMS was once again introduced in testing in February 2016, before the official global rollout started in June.
Multiple accounts
In February 2016, Facebook added support for multiple accounts in the apps.
Bot platform
2016 launch
In April 2016, Facebook announced a bot platform for Messenger, including an API to build chat bots to interact with users. News publisher bots "message subscribers directly with news and other information", while ride-sharing apps can offer a transportation option, hotel chains can answer questions about accommodations, and air travel companies can allow for check-ins, flight updates and travel changes.
2017 enhancements
At the 2017 Facebook F8 conference, Facebook launched a range of enhancements for bots:
- Bots in group chats: Bots can participate in group chats - not by conversing with the chat participants -- but by injecting notifications such as news updates, receipts, sports progress, and more.
- Chat extensions: Users can interact with dedicated apps, including play games, collaborate on music playlists, and book flights. In addition, Facebook launched a "Discovery" tab, featuring recently-used bots, bot categories, trending experiences and search functionality. A preview screen lets users see what each chat would do in a conversation.
- QR scan: Users can scan special, branded QR codes through Messenger's camera functionality, that take the user directly to a specific bot.
"M" assistant
In August 2015, Facebook announced M, an artificial intelligence virtual assistant for use in Messenger that is capable of automatically completing tasks for users, such as purchase items, arrange gift deliveries, book restaurants, and arrange travels. In April 2017, Facebook enabled M for users in the U.S. M scans chats for keywords and then suggests relevant actions. For example, writing "You owe me $20" will make M offer its payments system. The rollout of M suggestions was made official at Facebook's F8 conference on April 18, 2017.
"Home" messages panel
In June 2016, Facebook announced a "Home" button as a central location for sending and receiving messages. The Home button features the most recent messages, as well as a "Favorites" section for the contacts with the most frequent communication.
Encryption
In October 2016, Facebook introduced end-to-end encryption as an optional feature for Messenger users. It is available in an optional mode called "Secret Conversations" and uses the Signal Protocol. Through Secret Conversations, users can send "self-destructing" messages; messages that are removed permanently following an optional time period.
Instant Games
In November 2016, Facebook announced Instant Games, allowing users to quickly play games including Pac-Man, Space Invaders, EverWing and Words with Friends Frenzy inside Messenger. Games are asynchronous through high scores rather than directly at the same time, and are built on HTML5 rather than apps. In May 2017, Facebook announced the global rollout of Instant Games.
Messenger Day
Following an initial test in Poland in September 2016, Facebook launched "Messenger Day" in March 2017. Messenger Day, similar to Snapchat's Stories feature, gives the user the ability to share photos and videos with friends that automatically disappear after 24 hours.
Reactions and Mentions
In March 2017, Facebook introduced support for "Reactions" to individual messages, and "Mentions". Reactions let the user tap and hold on a message to add a reaction through an emoji, while Mentions let the user type @ in a group chat to give a particular user a direct notification.
Reception
In November 2014, the Electronic Frontier Foundation (EFF) listed Facebook Messenger (Facebook chat) on its Secure Messaging Scorecard. It received a score of 2 out of 7 points on the scorecard. It received points for having communications encrypted in transit and for having recently completed an independent security audit. It missed points because the communications were not encrypted with keys the provider didn't have access to, users could not verify contacts' identities, past messages were not secure if the encryption keys were stolen, the source code was not open to independent review, and the security design was not properly documented.
As stated by Facebook in its Help Center, there is no way to log out of the Facebook Messenger application. Instead, users can choose between different availability statuses, including "Appear as inactive", "Switch accounts", and "Turn off notifications". Media outlets have reported on a workaround, by pressing a "Clear data" option in the application's menu in Settings on Android devices, which returns the user to the log-in screen.
User growth
After being separated from the main Facebook app, Facebook Messenger had 600 million users in April 2015. This grew to 900 million in June 2016, 1 billion in July 2016, and 1.2 billion in April 2017.
