Line is a freeware app for instant communications on electronic devices such as smartphones, tablet computers, personal computers. Line users exchange texts, images and audio, conduct free VoIP conversations and video conferences. In addition, Line is a platform providing various services including digital wallet as Line Pay, news stream as Line Today, video on demand as Line TV, digital comic distribution as Line Manga and Line Webtoon; the service is operated by a subsidiary in Tokyo of Naver Corporation. Line launched in Japan in 2011, reaching 100 million users within eighteen months and 200 million users only six months later. Line became Japan's largest social network in 2013. In October 2014, Line announced that it had attracted 560 million users worldwide with 170 million active user accounts. In February 2015, it announced the 600 million users mark had been passed and 700 million were expected by the end of the year, it is the most popular messaging application in Japan. It is popular in Taiwan, Thailand and Indonesia.
Line was developed as a mobile application for Android and iOS smartphones. The service has since expanded to BlackBerry OS, Nokia Asha, Windows Phone, Firefox OS, iOS tablets, as a Chrome Browser Application. At one point, Line was available as a website; the application exists in versions for laptop and desktop computers using the Microsoft Windows and macOS platforms. Line began as a disaster response. In March 2011, the Tōhoku earthquake damaged Japan's telecommunications infrastructure nationwide, obliging employees at NHN Japan, a unit of South Korea's NHN Corporation, to rely on Internet-based resources to communicate; the company's engineers developed Line to facilitate this, the company released their app for public use in June. The application proved hugely popular, by late October, Line experienced an unexpected server overload. After concluding that the scalability process needed to be improved, NHN Japan chose to adopt HBase as the primary storage for user profiles and groups. Within eighteen months of its release, Line reached 100 million users.
On July 3, 2012, NHN Japan announced the new Line features Timeline. The features allowed users to share recent personal developments to a community of contacts in real-time, similar to the status updates in social networking services such as Facebook. On 6 February 2013, the success of Line led NHN Japan to announce a new spinoff company named Line Corporation which continues to develop Internet resources such as Line, the Naver Japan search portal, the Livedoor ISP and blog platform. Games, including those for the Line Game brand, remain under the auspices of Hangame Japan. A new joint venture named. At launch, the majority of Line Plus shares were held by the newly created Line Corporation with the remaining shares held by its Korean parent NHN Corporation. Line began in summer 2011 as a communication system for NHN Japan employees, it saw explosive growth when released to the public in June of that year. By 18 January 2013, Line had been downloaded 100 million times worldwide; the number expanded to 140 million by early July 2013 and to 200 million by July 21.
As of June 2016, Japan claimed 68 million users. As of February 2014, Indonesia had 20 million users, Taiwan 17 million, while India and Spain had 16 million each. NHN company representatives announced plans to reach 300 million by further expansion in East Asia and Chile. In April 2014, Naver announced that Line had reached 400 million worldwide users, by 2017 this had grown to 700 million. Line is an application that works on multiple platforms and has access via multiple personal computers; the application will give an option of address book syncing. This application has a feature to add friends through the use of QR codes, by line id, by shaking phones simultaneously; the application has a direct pop-out message box for reading and replying to make it easy for users to communicate. It can share photos and music with other users, send current or any specific location, voice audio, emojis and emoticons to friends. Users can see a real-time confirmation when messages are sent and received or use a hidden chat feature, which can hide and delete a chat history after a time set by the user.
The application makes free voice and video calls. Users can chat and share media in a group by creating and joining groups up to 500 people. Chats provide bulletin boards on which you can post and comment; this application has timeline and homepage features that allow users to post pictures and stickers on their homepages. Users can change their Line theme to the theme Line provides in the theme shop for free or users can buy other famous cartoon characters they like. Line has a feature, called a Snap movie, that users can use to record a stop motion video and add in provided background music. In January 2015, Line Taxi was released in Tokyo as a competitor to Uber. Line launched a new android app called "Popcorn buzz" in June 2015; the app facilitates group calls with up to 200 members. In June a new Emoji keyboard was released for iOS devices, which provides a Line-like experience with the possibility to add stickers. In September 2015 a new Android Launcher was released on the Play Store, helping the company to promote its own
Snapchat is a multimedia messaging app used globally, created by Evan Spiegel, Bobby Murphy, Reggie Brown, former students at Stanford University, developed by Snap Inc. Snapchat Inc. One of the principal features of Snapchat is that pictures and messages are only available for a short time before they become inaccessible to their recipients; the app has evolved from focusing on person-to-person photo sharing to presently featuring users' "Stories" of 24 hours of chronological content, along with "Discover", letting brands show ad-supported short-form content. Snapchat has become notable for representing a new, mobile-first direction for social media, places significant emphasis on users interacting with virtual stickers and augmented reality objects; as of February 2018, Snapchat has 187 million daily active users. According to documents and deposition statements, Reggie Brown brought the idea for a disappearing pictures application to Evan Spiegel because Spiegel had prior business experience.
Brown and Spiegel pulled in Bobby Murphy, who had experience coding. The three worked together for several months and launched Snapchat as "Picaboo" on the iOS operating system on July 8, 2011. Reggie Brown was ousted from the company months; the app was relaunched as Snapchat in September 2011, the team focused on usability and technical aspects, rather than branding efforts. One exception was the decision to keep a mascot designed by Brown, "Ghostface Chillah", named after Ghostface Killah of the hip-hop group Wu-Tang Clan. On May 8, 2012, Reggie Brown sent an email to Evan Spiegel during their senior year at Stanford, in which he offered to re-negotiate his equitable share regarding ownership of the company. Lawyers for Snapchat responded by insisting that he had never had any creative connection to the product; the attorneys accused Brown of committing fraud against Spiegel and Murphy by falsely claiming to be a product inventor. On behalf of their clients, the law firm concluded that Reggie Brown had made no contributions of value or worth, was therefore entitled to a share of nothing.
In September 2014, Brown settled with Spiegel and Murphy for $157.5 million and was credited as one of the original authors of Snapchat. In their first blog post, dated May 9, 2012, CEO Evan Spiegel described the company's mission: "Snapchat isn’t about capturing the traditional Kodak moment. It’s about communicating with the full range of human emotion — not just what appears to be pretty or perfect." He presented Snapchat as the solution to stresses caused by the longevity of personal information on social media, evidenced by "emergency detagging of Facebook photos before job interviews and photoshopping blemishes out of candid shots before they hit the internet". As of May 2012, 25 Snapchat images were being sent per second and, as of November 2012, users had shared over one billion photos on the Snapchat iOS app, with 20 million photos being shared per day; that same month, Spiegel cited problems with user base scalability as the reason why Snapchat was experiencing some difficulties delivering its images, known as "snaps", in real time.
Snapchat was released as an Android app on October 29, 2012. In June 2013, Snapchat version 5.0, dubbed "Banquo", was released for iOS. The updated version introduced several speed and design enhancements, including swipe navigation, double-tap to reply, an improved friend finder, in-app profiles; the name is a reference to the ghostly hero from Shakespeare's Macbeth, a character in the play, seen to be victorious over evil. In June 2013, Snapchat introduced Snapkidz for users under 13 years of age. Snapkidz was part of the original Snapchat application and was activated when the user provided a date of birth to verify his/her age. Snapkidz allowed children to take snaps and draw on them, but they could not send snaps to other users and could only save snaps locally on the device being used. According to Snapchat's published statistics, as of May 2015, the app's users were sending 2 billion videos per day, reaching 6 billion by November. By 2016, Snapchat had hit 10 billion daily video views. In May 2016, Snapchat raised $1.81 billion in equity offering, suggesting strong investor interest in the company.
By May 31, 2016, the app had 10 million daily active users in the United Kingdom. In February 2017, Snapchat had 160 million daily active users, growing to 166 million in May. In September 2016, Snapchat Inc. was renamed Snap Inc. to coincide with the introduction of the company's first hardware product, Spectacles— smartglasses with a built-in camera that can record 10 seconds of video at a time. On February 20, 2017, Spectacles became available for purchase online. Snapchat is used for creating multimedia messages referred to as "snaps". Snaps can be directed to selected contacts, or to a semi-public "Story" or a public "Story" called "Our Story"; the ability to send video snaps was added as a feature option in December 2012. By holding down on the photo button while inside the app, a video of up to ten seconds in length can be captured. Spiegel explained that this process allowed the video data to be compressed into the size of a photo. A update allowed the ability to record indefinitely, but are still segmented into 10 second intervals.
After a single viewing, the video disappears by default. On May 1, 2014, the ability to communicate via video chat was added. Direct messaging features were included in the update, allowing users to send ephemeral text messages to friends and family while saving any needed information by clicking on it.. According to CIO, Snapchat uses real-time marketing concepts
Internet Relay Chat
Internet Relay Chat is an application layer protocol that facilitates communication in the form of text. The chat process works on a client/server networking model. IRC clients are computer programs that users can install on their system or web based applications running either locally in the browser or on 3rd party server; these clients communicate with chat servers to transfer messages to other clients. IRC is designed for group communication in discussion forums, called channels, but allows one-on-one communication via private messages as well as chat and data transfer, including file sharing. Client software is available for every major operating system; as of April 2011, the top 100 IRC networks served more than half a million users at a time, with hundreds of thousands of channels operating on a total of 1,500 servers out of 3,200 servers worldwide. IRC usage has been declining since 2003, losing 60% of its users and half of its channels. IRC was created by Jarkko Oikarinen in August 1988 to replace a program called MUT on a BBS called OuluBox at the University of Oulu in Finland, where he was working at the Department of Information Processing Science.
Jarkko intended to extend the BBS software he administered, to allow news in the Usenet style, real time discussions and similar BBS features. The first part he implemented was the chat part, which he did with borrowed parts written by his friends Jyrki Kuoppala and Jukka Pihl; the first IRC network was running on a single server named tolsun.oulu.fi. Oikarinen found inspiration in a chat system known as Bitnet Relay, which operated on the BITNET. Jyrki Kuoppala pushed Jarkko to ask Oulu University to free the IRC code so that it could be run outside of Oulu, after they got it released, Jyrki Kuoppala installed another server; this was the first "irc network". Jarkko got some friends at the Helsinki University and Tampere University to start running IRC servers when his number of users increased and other universities soon followed. At this time Jarkko realized that the rest of the BBS features wouldn't fit in his program. Jarkko got in touch with people at the University of Oregon State University.
They wanted to connect to the Finnish network. They had obtained the program from one of Jarkko's friends, Vijay Subramaniam—the first non-Finnish person to use IRC. IRC grew larger and got used on the entire Finnish national network—Funet—and connected to Nordunet, the Scandinavian branch of the Internet. In November 1988, IRC had spread across the Internet and in the middle of 1989, there were some 40 servers worldwide. In August 1990, the first major disagreement took place in the IRC world; the "A-net" included a server named eris.berkeley.edu. It required no passwords and had no limit on the number of connects; as Greg "wumpus" Lindahl explains: "it had a wildcard server line, so people were hooking up servers and nick-colliding everyone". The "Eris Free Network", EFnet, made the eris machine the first to be Q-lined from IRC. In wumpus' words again: "Eris refused to remove that line, it wasn't much of a fight. A-net was formed with the eris servers, EFnet was formed with the non-eris servers.
History showed most users went with EFnet. Once ANet disbanded, the name EFnet became meaningless, once again it was the one and only IRC network, it is around that time that IRC was used to report on the 1991 Soviet coup d'état attempt throughout a media blackout. It was used in a similar fashion during the Gulf War. Chat logs of these and other events are kept in the ibiblio archive. Another fork effort, the first that made a big and lasting difference, was initiated by'Wildthang' in the U. S. October 1992, it was meant to be just a test network to develop bots on but it grew to a network "for friends and their friends". In Europe and Canada a separate new network was being worked on and in December the French servers connected to the Canadian ones, by the end of the month, the French and Canadian network was connected to the US one, forming the network that came to be called "The Undernet"; the "undernetters" wanted to take ircd further in an attempt to make it less bandwidth consumptive and to try to sort out the channel chaos that EFnet started to suffer from.
For the latter purpose, the Undernet implemented timestamps, new routing and offered the CService—a program that allowed users to register channels and attempted to protect them from troublemakers. The first server list presented, from February 15, 1993, includes servers from USA, France and Japan. On August 15, the new user count record was set to 57 users. In May 1993, RFC 1459 was published and details a simple protocol for client/server operation, one-to-one and one-to-many conversations, it is notable that a significant number of extensions like CTCP, colors and formats are not included in the protocol specifications, nor is character encoding, which led various implementations of servers and clients to diverge. In fact, software implementation varied from one network to the other, each network implementing their own policies and standards in their own code bases. During the summer of 1994, the Undernet was itself forked; the new network was called DALnet, formed for better user service and more user and channel protections.
One of the more significant changes in DALnet was use of lo
The Palace (computer program)
The Palace is a computer program to access graphical chat room servers, called palaces, in which users may interact with one another using graphical avatars overlaid on a graphical backdrop. The software concept was created by Jim Bumgardner and produced by Time Warner Interactive in 1994, was first opened to the public in November 1995. While there is no longer any official support for the original program, a new client has been developed and is maintained by Jameson Heesen. Many chat servers can be found on the Palace Portal Live Directory. Palace clients and servers are available for Mac OS 9, Mac OS X, Microsoft Windows; the Palace has a flexible avatar system that allows users to combine small transparent images to create a unique look. Once the member has created an avatar, the member can pick up various pieces of clothing or other items, such as hats, cans of soda, candy bars, bicycles, or hand tools. Dollz originated in The Palace. By default, users are represented by spherical smiley face emoticons, but can wear bitmaps called props.
User messages appear as chat bubbles above their avatar, similar to those in comic books, stored in a chat log. Each room in a palace is represented by a large image. By clicking on certain areas in a room called doors, users can travel either to different rooms in the same palace, another palace server, or an address leading to a different service, such as websites and email. In some rooms, users are allowed to paint on the backdrop using a simple suite of drawing tools similar to oekaki; the Palace was created by Jim Bumgardner and produced by Time Warner Interactive in 1994. Bumgardner incorporated many features of Idaho, an in-house authoring tool he had developed for making multimedia CD-ROMs. One of the features of Idaho was a Forth-like programming language; the name is a play on the word "script" in Pig Latin. One of the unique features of the Palace for its time was that the server software was given away for free and ran on consumer PCs, rather than being housed in a central location.
From around 1997, artists began to use the Palace as a site for experimental live performance. Notably, the group Desktop Theatre staged interventions and performances in their own and public Palaces from 1997 until 2002. In 1997 they presented "waitingforgodot.com" at the Third Annual Digital Storytelling Festival, which took an interesting turn when another Palatian changed their name to Godot and arrived in the performance. Other artists working in The Palace include Avatar Body Collision. Palace Chat's popularity peaked around 1999-2000, when nu metal band Korn had their own palace chat room that fans could download from korn.com. Palace's popularity at this time could be attributed to a palace which focused on the cartoon South Park, as well as the Sci Fi channel's Mothership palace. There was a link to the South Park palace on the Comedy Central website at the time; the Palace was the subject of a number of sales between companies until 2001, when Open Text Corporation purchased the rights to the Palace software and technology as part of a bankruptcy settlement.
The software is unsupported by Open Text or any of its previous owners, many members of the community now consider the software abandonware and provide support for existing versions on unofficial web sites. The original thepalace.com domain was bought by a long time Palace user, is now used as a directory for other sites. Official Palace software development ceased when Communities.com declared bankruptcy, but at least four groups are working on Palace protocol compatible clients. One of the biggest contributions came from Ruben Pizarro, known as oORubenOo only 13 years old at the time, was able to reverse engineer the most important protocol packets talk & xtlk for proper communication between the client and server. All of these new clients support improved high-color avatars, larger room backgrounds, modern sound formats, are designed for modern operating systems. However, there are some drawbacks to the new clients, such as not being compatible with older clients, many users have chosen to remain with older alternatives.
One of the first comprehensive psychological studies of avatar communities, conducted by John Suler, took place at the Palace. This collection of essays, entitled Life at the Palace, consists of an analysis of Palace history, social relationships, "addiction," and deviance. Suler's work focused on the unique aspects of interacting in a graphical space. Signing into The Palace does not require any registration or personal information. To begin chatting, users download the client, set their user handle and login to a server. A child filter is enabled on the client by default, which filters out chat servers with an Adult ranking and inappropriate language used in chat rooms. PalaceChat, created by Jameson Heesen, which supports all original features of The Palace, as well as high-quality backgrounds and avatars, larger rooms and videos; this is the primary client in use. OpenPalace, an open source, Adobe Flash implementation by Brian McKelvey, gaining popularity and receiving much support and feedback from many Palace users.
Linpal, an open source Linux client using GTK+. Phalanx, by Brainhouse Laboratories; the Manor, written by a former Palace lead developer. The Manor includes embedded Python for room scripting with an encrypted data stream. Supports importing Palace avatars. Both new incarnations of The Palace support larger room sizes and 32-bit color avat
Facebook Messenger is a messaging app and platform. Developed as Facebook Chat in 2008, the company revamped its messaging service in 2010, 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, separated the messaging functionality from the main Facebook app, requiring users to use the web interface or download one of the standalone apps. Users can send messages and exchange photos, stickers and files, as well as react to other users' messages and interact with bots; the service supports voice and video calling. The standalone apps support using multiple accounts, conversations with optional end-to-end encryption, playing games. Following tests of a new instant messaging platform on Facebook in March 2008, the feature, then-titled "Facebook Chat", was released to users in April 2008. Facebook revamped its messaging platform in November 2010, 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 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 at old Android phones and regions where high-speed Internet is not available. 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, 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 releasing the program; the program was discontinued in March 2014. A Firefox web browser add-on was released in December 2012, but was discontinued in March 2014. In December 2017, Facebook announced Messenger Kids, a new app aimed for persons under 13 years of age; the app comes with some differences compared to the standard version. The following is a table of features available in Facebook Messenger, as well as their geographical coverage and what devices they are available on: In January 2017, Facebook announced that it was testing showing advertisements in Facebook Messenger's home feed. At the time, the testing was limited to a "small number of users in Australia and Thailand", with the ad format being swipe-based carousel ads. In July, the company announced. Stan Chudnovsky, head of Messenger, told VentureBeat that "We’ll start slow...
When the average user can be sure to see them we don’t know because we’re just going to be data-driven and user feedback-driven on making that decision". Facebook told TechCrunch that the advertisements' placement in the inbox depends on factors such as thread count, phone screen size, pixel density. In a TechCrunch editorial by Devin Coldewey, he described the ads as "huge" in the space they occupy, "intolerable" in the way they appear in the user interface, "irrelevant" due to the lack of context. Coldewey finished by writing "Advertising is how things get paid for on the internet, including TechCrunch, so I’m not an advocate of eliminating it or blocking it altogether, but bad advertising experiences can spoil a good app like Messenger. Messaging is a personal, purposeful use case and these ads are a bad way to monetize it." In November 2014, the Electronic Frontier Foundation listed Facebook Messenger 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 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, 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", "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. 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, 1.2 billion in April 2017.

Jingle is an extension to the Extensible Messaging and Presence Protocol which adds peer-to-peer session control for multimedia interactions such as in Voice over IP or videoconferencing communications. It was designed by the XMPP Standards Foundation; the multimedia streams. If needed, NAT traversal is assisted using Interactive Connectivity Establishment; as of December 2009, the proposed Jingle specification had not yet been approved by the XMPP Standards Foundation, but is now a Draft Standard, meaning: "Implementations are encouraged and the protocol is appropriate for deployment in production systems, but some changes to the protocol are possible before it becomes a Final Standard."The libjingle library, used by Google Talk to implement Jingle, has been released to the public under a BSD license. It implements both the older, pre-standard version. Asterisk PBX Coccinella Conversations Empathy FreeSWITCH Gajim from 0.14 Google Talk for Gmail, Windows iChat for Apple OS X Jitsi KDE Telepathy Kopete Miranda IM Monal IM-Client for iOS Pidgin Psi QIP Infium Yate/YateClient supports Jingle in both client and server mode and file transfer call transfer and DTMF.

IGap is a free open-source instant messaging application for smart phones and personal computers. IGap provides all users to interact with each other and exchange information through text, video and other types of messages; this Iranian messenger has featured P2P-based voice calls for the first time in the country and contribute users over the internet.iGap exists for Android, iOS, desktop systems. According to the producers, two AES keys are used in iGap to encrypt symmetrically; the first is for the second one is for the server-based. In addition to the encrypted system, all connections between server and users will be covered with the activated SSL 2048. Thus, it would be impossible to eavesdrop the information on the route; the voice call possibility in iGap follows the most modern technology in the world, used in Signal as well. In this tech for voice call, server is called P2P literally. Mohammad Rasoul Kazemi founder of IGap has declared in an interview: "All messages and files in iGap have been encrypted and no one has access to them,I reward 1bln tomans to anyone who can hack the encrypted information of the iGap messaging application,".
IGap has published client-based codes and make them available for everyone and stepped forward in the open-source community in the world by holding a competitive event for programmers and developers. The whole codes of Android and iOS version and the iGap programming applicable interface were made available on GitHub for interested developers; the Iranian leader Ali Khamenei referred to this messenger on his personal website. and Mohammad-Javad Azari Jahromi as the ICT Minister of Iran has joined this messaging application in September 2017 in order to support local social networking. Earlier, the Minister has claimed to support local Messengers when he was deputy of the ICT Minister.
