Text messaging
Text messaging, or texting, is the act of composing and sending electronic messages, typically consisting of alphabetic and numeric characters, between two or more users of mobile devices, desktops/laptops, or another type of compatible computer. Text messages may be sent over a cellular network or may also be sent via satellite or Internet connection.

The term originally referred to messages sent using the Short Message Service (SMS). It has grown beyond alphanumeric text to include multimedia messages using the Multimedia Messaging Service (MMS) and Rich Communication Services (RCS), which can contain digital images, videos, and sound content, as well as ideograms known as emoji (happy faces, sad faces, and other icons), and instant messenger applications (usually the term is used when on mobile devices).
Text messages are used for personal, family, business, and social purposes. Governmental and non-governmental organizations use text messaging for communication between colleagues. In the 2010s, the sending of short informal messages became an accepted part of many cultures, as happened earlier with emailing.[1] This makes texting a quick and easy way to communicate with friends, family, and colleagues, including in contexts where a call would be impolite or inappropriate (e.g., calling very late at night or when one knows the other person is busy with family or work activities). Like e-mail and voicemail, and unlike calls (in which the caller hopes to speak directly with the recipient), texting does not require the caller and recipient to both be free at the same moment; this permits communication even between busy individuals. Text messages can also be used to interact with automated systems, for example, to order products or services from e-commerce websites or to participate in online contests. Advertisers and service providers use direct text marketing to send messages to mobile users about promotions, payment due dates, and other notifications instead of using postal mail, email, or voicemail.
History[edit]
The electrical telegraph systems, developed in the early 19th century, used electrical signals to send text messages. In the late 19th century, wireless telegraphy was developed using radio waves.
In 1933, the German Reichspost (Reich postal service) introduced the first "telex" service.[2][3]
The University of Hawaii began using radio to send digital information as early as 1971, using ALOHAnet. Friedhelm Hillebrand conceptualised SMS in 1984 while working for Deutsche Telekom. Sitting at a typewriter at home, Hillebrand typed out random sentences and counted every letter, number, punctuation mark, and space. Almost every time, the messages contained fewer than 160 characters, thus giving the basis for the limit one could type via text messaging.[4] With Bernard Ghillebaert of France Télécom, he developed a proposal for the GSM (Groupe Spécial Mobile) meeting in February 1985 in Oslo.[5] The first technical solution evolved in a GSM subgroup under the leadership of Finn Trosby. It was further developed under the leadership of Kevin Holley and Ian Harris (see Short Message Service).[6] SMS forms an integral part of Signalling System No. 7 (SS7).[7] Under SS7, it is a "state" with 160 characters of data, coded in the ITU-T "T.56" text format, that has a "sequence lead in" to determine different language codes and may have special character codes that permit, for example, sending simple graphs as text. This was part of ISDN (Integrated Services Digital Network), and since GSM is based on this, it made its way to the mobile phone. Messages could be sent and received on ISDN phones, and these can send SMS to any GSM phone. The possibility of doing something is one thing; implementing it is another, but systems existed in 1988 that sent SMS messages to mobile phones (compare ND-NOTIS).
SMS messaging was used for the first time on 3 December 1992,[8] at the Three Tuns Public House in Reading, Berkshire,[9] when Neil Papworth, a 22-year-old test engineer for Sema Group in the UK[10] (now Airwide Solutions),[11] used a personal computer to send the text message "Merry Christmas" via the Vodafone network to the phone of Richard Jarvis,[12][13] who was at a party in Newbury, Berkshire, which had been organized to celebrate the event. Modern SMS text messaging is usually sent from one mobile phone to another. Finnish Radiolinja became the first network to offer a commercial person-to-person SMS text messaging service in 1994. When Radiolinja's domestic competitor, Telecom Finland (now part of TeliaSonera), also launched SMS text messaging in 1995 and the two networks offered cross-network SMS functionality, Finland became the first nation where SMS text messaging was offered on a competitive as well as a commercial basis. GSM was allowed in the United States, but the radio frequencies were blocked and awarded to US "Carriers" to use US technology, which limited development of mobile messaging services in the US. The GSM in the US had to use a frequency allocated for private communication services (PCS) – what the ITU frequency régime had blocked for DECT (Digital Enhanced Cordless Telecommunications) – a 1,000-foot range picocell, but it survived. American Personal Communications (APC), the first GSM carrier in America, provided the first text-messaging service in the United States. Sprint Telecommunications Venture, a partnership of Sprint Corp. and three large cable-TV companies, owned 49 percent of APC. The Sprint venture was the largest single buyer at a government-run spectrum auction that raised $7.7 billion in 2005 for PCS licenses. APC operated under the brand name Sprint Spectrum and launched its service on 15 November 1995, in Washington, D.C., and Baltimore, Maryland. Vice President Al Gore in Washington, D.C., made the initial phone call to launch the network, calling Mayor Kurt Schmoke in Baltimore.[14]
Initial growth of text messaging worldwide was slow, with customers in 1995 sending on average only 0,4 messages per GSM customer per month.[15] One factor in the slow take-up of SMS was that operators were slow to set up charging systems, especially for prepaid subscribers, and to eliminate billing fraud, which was possible by changing SMSC settings on individual handsets to use the SMSCs of other operators. Over time, this issue was eliminated by switch billing instead of billing at the SMSC and by new features within SMSCs that allowed the blocking of foreign mobile users sending messages through them. SMS is available on a wide range of networks, including 3G networks. However, not all text-messaging systems use SMS; some notable alternate implementations of the concept include J-Phone's SkyMail and NTT Docomo's Short Mail, both in Japan. E-mail messaging from phones, as popularized by NTT Docomo's i-mode and the RIM BlackBerry, also typically use standard mail protocols such as SMTP over TCP/IP.[16] As of 2007, text messaging was the most widely used mobile data service, with 74% of all mobile phone users worldwide, or 2.4 billion out of 3.3 billion phone subscribers, being active users of the Short Message Service at the end of 2007. In countries such as Finland, Sweden, and Norway, over 85% of the population used SMS. The European average was about 80%, and North America was rapidly catching up, with over 60% active users of SMS by end of 2008. The largest average usage of the service by mobile phone subscribers occurs in the Philippines, with an average of 27 texts sent per day per subscriber.
In popular culture[edit]
Records and competition[edit]
The Guinness Book of World Records has a world record for text messaging, currently held by Sonja Kristiansen of Norway. Kristiansen keyed in the official text message, as established by Guinness, in 37.28 seconds.[182] The message is, "The razor-toothed piranhas of the genera Serrasalmus and Pygocentrus are the most ferocious freshwater fish in the world. In reality, they seldom attack a human."[182] In 2005, the record was held by a 24-year-old Scottish man, Craig Crosbie, who completed the same message in 48 seconds, beating the previous time by 19 seconds.[183] The Book of Alternative Records lists Chris Young of Salem, Oregon as the world-record holder for the fastest 160-character text message where the contents of the message are not provided ahead of time. His record of 62.3 seconds was set on 23 May 2007.[184]
Elliot Nicholls of Dunedin, New Zealand currently holds the world record for the fastest blindfolded text messaging. A record of a 160-letter text in 45 seconds while blindfolded was set on 17 November 2007, beating the old record of 1-minute 26 seconds set by an Italian in September 2006.[185] Andrew Acklin of Ohio is credited with the world record for most text messages sent or received in a single month, with 200,052. His accomplishments were first in the World Records Academy and later followed up by Ripley's Believe It Or Not 2010: Seeing Is Believing. He has been acknowledged by The Universal Records Database for the most text messages in a single month; however, this has since been broken twice and as of 2010 was listed as 566607 messages by Fred Lindgren.[186]
In January 2010, LG Electronics sponsored an international competition, the LG Mobile World Cup, to determine the fastest pair of texters. The winners were a team from South Korea, Ha Mok-min and Bae Yeong-ho.[187] On 6 April 2011, SKH Apps released an iPhone app, iTextFast, to allow consumers to test their texting speed and practice the paragraph used by Guinness Book of World Records. As of 2011, best time listed on Game Center for that paragraph is 34.65 seconds.[188]
Morse code[edit]
A few competitions have been held between expert Morse code operators and expert SMS users.[189] Several mobile phones have Morse code ring tones and alert messages. For example, many Nokia mobile phones have an option to beep "S M S" in Morse code when it receives a short message. Some of these phones could also play the Nokia slogan "Connecting people" in Morse code as a message tone.[190] There are third-party applications available for some mobile phones that allow Morse input for short messages.[191][192][193]
