Social media

Social media refers to the means of interactions among people in which they create, share, and/or exchange information and ideas in virtual communities andnetworks.Andreas Kaplan and Michael Haenlein define social media as "a group of Internet-based applications that build on the ideological and technological foundations ofWeb 2.0, and that allow the creation and exchange of user-generated content."Furthermore, social media depends on mobile and web-based technologies to create highly interactive platforms through which individuals and communities share, co-create, discuss, and modify user-generated content. It introduces substantial and pervasive changes to communication between organizations, communities, and individuals.

Social media differentiates from traditional/industrial media in many aspects such as quality,reach, frequency, usability, immediacy, and permanence. There are many effects that stem from internet usage. According to Nielsen, internet users continue to spend more time with social media sites than any other type of site. At the same time, the total time spent on social media in the U.S. across PC and mobile devices increased by 37 percent to 121 billion minutes in July 2012 compared to 88 billion minutes in July 2011. For content contributors, the benefits of participating in social media have gone beyond simply social sharing to building reputation and bringing in career opportunities and monetary income, as discussed in Tang, Gu, and Whinston (2012).

Much of the criticism of social media are about its exclusiveness[citation needed] as most sites do not allow the transfer of information from one to another, disparity of information available, issues with trustworthiness and reliability of information presented, concentration, ownership of media content, and the meaning of interactions created by social media. However, it is also argued that social media has positive effects such as allowing the democratization of the internetwhile also allowing individuals to advertise themselves and form friendships.

Most people[who?] associate social media with positive outcomes[citation needed], yet this is not always the case. Due to the increase in social media websites, there seems to be a positive correlation between the usage of such media with cyber-bullying, online sexual predators, and the decrease in face-to-face interactions. Social media may expose children to images of alcohol, tobacco, and sexual behaviors[relevant? ].

Geocities, created in 1994, was one of the first social media sites. The concept was for users to create their own websites, characterized by one of six "cities" that were known for certain characteristics.

Social impact

The Internet has enabled entirely new forms of social interaction, activities, and organizing, thanks to its basic features such as widespread usability and access. In the first decade of the 21st century, the first generation is raised with widespread availability of Internet connectivity, bringing consequences and concerns in areas such as personal privacy and identity, and distribution of copyrighted materials. These "digital natives" face a variety of challenges that were not present for prior generations.

Social networking and entertainment

Many people use the World Wide Web to access news, weather and sports reports, to plan and book vacations and to find out more about their interests. People use chat, messaging and email to make and stay in touch with friends worldwide, sometimes in the same way as some previously had pen pals. The Internet has seen a growing number of Web desktops, where users can access their files and settings via the Internet.

Social networking websites such asFacebookTwitter, and MySpace have created new ways to socialize and interact. Users of these sites are able to add a wide variety of information to pages, to pursue common interests, and to connect with others. It is also possible to find existing acquaintances, to allow communication among existing groups of people. Sites likeLinkedIn foster commercial and business connections. YouTube and Flickr specialize in users' videos and photographs.

The Internet has been a major outlet for leisure activity since its inception, with entertaining social experiments such asMUDs and MOOs being conducted on university servers, and humor-related Usenetgroups receiving much traffic. Today, manyInternet forums have sections devoted to games and funny videos; short cartoons in the form of Flash movies are also popular. Over 6 million people use blogs or message boards as a means of communication and for the sharing of ideas. The Internet pornography and online gambling industries have taken advantage of the World Wide Web, and often provide a significant source of advertising revenue for other websites.[61]Although many governments have attempted to restrict both industries' use of the Internet, in general this has failed to stop their widespread popularity.[62]

Another area of leisure activity on the Internet is multiplayer gaming.[63] This form of recreation creates communities, where people of all ages and origins enjoy the fast-paced world of multiplayer games. These range from MMORPG to first-person shooters, from role-playing video games toonline gambling. While online gaming has been around since the 1970s, modern modes of online gaming began with subscription services such as GameSpy and MPlayer.[64]Non-subscribers were limited to certain types of game play or certain games. Many people use the Internet to access and download music, movies and other works for their enjoyment and relaxation. Free and fee-based services exist for all of these activities, using centralized servers and distributed peer-to-peer technologies. Some of these sources exercise more care with respect to the original artists' copyrights than others.

Internet usage has been correlated to users' loneliness.[65] Lonely people tend to use the Internet as an outlet for their feelings and to share their stories with others, such as in the "I am lonely will anyone speak to me" thread.

Cybersectarianism is a new organizational form which involves: "highly dispersed small groups of practitioners that may remain largely anonymous within the larger social context and operate in relative secrecy, while still linked remotely to a larger network of believers who share a set of practices and texts, and often a common devotion to a particular leader. Overseas supporters provide funding and support; domestic practitioners distribute tracts, participate in acts of resistance, and share information on the internal situation with outsiders. Collectively, members and practitioners of such sects construct viable virtual communities of faith, exchanging personal testimonies and engaging in collective study via email, on-line chat rooms and web-based message boards."[66]

Cyberslacking can become a drain on corporate resources; the average UK employee spent 57 minutes a day surfing the Web while at work, according to a 2003 study by Peninsula Business Services.[67]Internet addiction disorder is excessive computer use that interferes with daily life. Psychologist Nicolas Carr believe that Internet use has other effects on individuals, for instance improving skills of scan-reading and interfering with the deep thinking that leads to true creativity.[68]

Electronic business

Electronic business (E-business) involves business processes spanning the entire value chain: electronic purchasing and supply chain management, processing orders electronically, handling customer service, and cooperating with business partners. E-commerce seeks to add revenue streams using the Internet to build and enhance relationships with clients and partners.

According to research firm IDC, the size of total worldwide e-commerce, when global business-to-business and -consumer transactions are added together, will equate to $16 trillion in 2013. IDate, another research firm, estimates the global market for digital products and services at $4.4 trillion in 2013. A report by Oxford Economics adds those two together to estimate the total size of thedigital economy at $20.4 trillion, equivalent to roughly 13.8% of global sales.[69]

While much has been written of the economic advantages of Internet-enabled commerce, there is also evidence that some aspects of the Internet such as maps and location-aware services may serve to reinforce economic inequality and the digital divide.[70] Electronic commerce may be responsible forconsolidation and the decline of mom-and-popbrick and mortar businesses resulting in increases in income inequality.[71][72][73]

Telecommuting

Remote work is facilitated by tools such asgroupwarevirtual private networks,conference callingvideoconferencing, andVoice over IP (VOIP). It can be efficient and useful for companies as it allows workers to communicate over long distances, saving significant amounts of travel time and cost. As broadband Internet connections become more commonplace, more and more workers have adequate bandwidth at home to use these tools to link their home to their corporate intranet and internal phone networks.

Crowdsourcing

Internet provides a particularly good venue for crowdsourcing (outsourcing tasks to a distributed group of people) since individuals tend to be more open in web-based projects where they are not being physically judged or scrutinized and thus can feel more comfortable sharing.

Crowdsourcing systems are used to accomplish a variety of tasks. For example, the crowd may be invited to develop a new technology, carry out a design task, refine or carry out the steps of an algorithm (seehuman-based computation), or help capture, systematize, or analyze large amounts of data (see also citizen science).

Wikis have also been used in the academic community for sharing and dissemination of information across institutional and international boundaries.[74] In those settings, they have been found useful for collaboration on grant writingstrategic planning, departmental documentation, and committee work.[75] The United States Patent and Trademark Office uses a wiki to allow the public to collaborate on finding prior artrelevant to examination of pending patent applications. Queens, New York has used a wiki to allow citizens to collaborate on the design and planning of a local park.[76]

The English Wikipedia has the largest user base among wikis on the World Wide Web[77]and ranks in the top 10 among all Web sites in terms of traffic.[78]

Politics and political revolutions

The Internet has achieved new relevance as a political tool. The presidential campaign ofHoward Dean in 2004 in the United States was notable for its success in soliciting donation via the Internet. Many political groups use the Internet to achieve a new method of organizing in order to carry out their mission, having given rise to Internet activism, most notably practiced by rebels in the Arab Spring.[79][80]

The New York Times suggested that social media websites, such as Facebook and Twitter, helped people organize the political revolutions in Egypt where it helped certain classes of protesters organize protests, communicate grievances, and disseminate information.[81]

The potential of the Internet as a civic tool of communicative power was thoroughly explored by Simon R. B. Berdal in his thesis of 2004:

As the globally evolving Internet provides ever new access points to virtual discourse forums, it also promotes new civic relations and associations within which communicative power may flow and accumulate. Thus, traditionally ... national-embedded peripheries get entangled into greater, international peripheries, with stronger combined powers... The Internet, as a consequence, changes the topology of the "centre-periphery" model, by stimulating conventional peripheries to interlink into "super-periphery" structures, which enclose and "besiege" several centres at once.[82]

Berdal, therefore, extends the Habermasiannotion of the Public sphere to the Internet, and underlines the inherent global and civic nature that intervowen Internet technologies provide. To limit the growing civic potential of the Internet, Berdal also notes how "self-protective measures" are put in place by those threatened by it:

If we consider China’s attempts to filter "unsuitable material" from the Internet, most of us would agree that this resembles a self-protective measure by the system against the growing civic potentials of the Internet. Nevertheless, both types represent limitations to "peripheral capacities". Thus, the Chinese government tries to prevent communicative power to build up and unleash (as the 1989 Tiananmen Square uprising suggests, the government may find it wise to install "upstream measures"). Even though limited, the Internet is proving to be an empowering tool also to the Chinese periphery: Analysts believe that Internet petitions have influenced policy implementation in favour of the public’s online-articulated will ...[82]

Philanthropy

The spread of low-cost Internet access in developing countries has opened up new possibilities for peer-to-peer charities, which allow individuals to contribute small amounts to charitable projects for other individuals. Websites, such as DonorsChoose andGlobalGiving, allow small-scale donors to direct funds to individual projects of their choice.

A popular twist on Internet-based philanthropy is the use of peer-to-peer lending for charitable purposes. Kivapioneered this concept in 2005, offering the first web-based service to publish individual loan profiles for funding. Kiva raises funds for local intermediary microfinance organizations which post stories and updates on behalf of the borrowers. Lenders can contribute as little as $25 to loans of their choice, and receive their money back as borrowers repay. Kiva falls short of being a pure peer-to-peer charity, in that loans are disbursed before being funded by lenders and borrowers do not communicate with lenders themselves.[83][84]

However, the recent spread of low cost Internet access in developing countries has made genuine international person-to-person philanthropy increasingly feasible. In 2009 the US-based nonprofit Zidisha tapped into this trend to offer the first person-to-person microfinance platform to link lenders and borrowers across international borders without intermediaries. Members can fund loans for as little as a dollar, which the borrowers then use to develop business activities that improve their families' incomes while repaying loans to the members with interest. Borrowers access the Internet via public cybercafes, donated laptops in village schools, and even smart phones, then create their own profile pages through which they share photos and information about themselves and their businesses. As they repay their loans, borrowers continue to share updates and dialogue with lenders via their profile pages. This direct web-based connection allows members themselves to take on many of the communication and recording tasks traditionally performed by local organizations, bypassing geographic barriers and dramatically reducing the cost of microfinance services to the entrepreneurs.[85]

Censorship

Internet censorship by country[86][87][88]
  Pervasive censorship
  Substantial censorship
  Selective censorship
  Changing situation
  Little or no censorship
  Not classified / no data

Some governments, such as those of Burma,IranNorth Korea, the Mainland ChinaSaudi Arabia, and the United Arab Emirates restrict what people in their countries can access on the Internet, especially political and religious content. This is accomplished through software that filters domains and content so that they may not be easily accessed or obtained without elaborate circumvention.[89]

In Norway, Denmark, Finland, and Sweden, major Internet service providers have voluntarily, possibly to avoid such an arrangement being turned into law, agreed to restrict access to sites listed by authorities. While this list of forbidden URLs is supposed to contain addresses of only known child pornography sites, the content of the list is secret.[90] Many countries, including the United States, have enacted laws against the possession or distribution of certain material, such as child pornography, via the Internet, but do not mandate filtering software. There are many free and commercially available software programs, called content-control software, with which a user can choose to block offensive websites on individual computers or networks, in order to limit a child's access to pornographic materials or depiction of violence.

History of Internet


Research into packet switching started in the early 1960s and packet switched networks such as Mark I at NPL in the UK,[8]ARPANET,CYCLADES,[9][10]Merit Network,[11]Tymnet, and Telenet, were developed in the late 1960s and early 1970s using a variety of protocols. The ARPANET in particular led to the development of protocols for internetworking, where multiple separate networks could be joined together into a network of networks.[citation needed]

The first two nodes of what would become the ARPANET were interconnected betweenLeonard Kleinrock's Network Measurement Center at the UCLA's School of Engineering and Applied Science and Douglas Engelbart'sNLS system at SRI International (SRI) inMenlo Park, California, on 29 October 1969.[12] The third site on the ARPANET was the Culler-Fried Interactive Mathematics center at the University of California at Santa Barbara, and the fourth was the University of Utah Graphics Department. In an early sign of future growth, there were already fifteen sites connected to the young ARPANET by the end of 1971.[13][14] These early years were documented in the 1972 film Computer Networks: The Heralds of Resource Sharing.

Early international collaborations on ARPANET were sparse. For various political reasons, European developers were concerned with developing the X.25networks.[15] Notable exceptions were theNorwegian Seismic Array (NORSAR) in June 1973,[16] followed in 1973 by Sweden with satellite links to the Tanum Earth Station andPeter T. Kirstein's research group in the UK, initially at the Institute of Computer Science,University of London and later at University College London.[citation needed]

In December 1974, RFC 675 – Specification of Internet Transmission Control Program, by Vinton Cerf, Yogen Dalal, and Carl Sunshine, used the term internet as a shorthand forinternetworking and later RFCs repeat this use.[17] Access to the ARPANET was expanded in 1981 when the National Science Foundation (NSF) developed the Computer Science Network (CSNET). In 1982, theInternet Protocol Suite (TCP/IP) was standardized and the concept of a world-wide network of fully interconnected TCP/IP networks called the Internet was introduced.

T3 NSFNET Backbone, c. 1992

TCP/IP network access expanded again in 1986 when the National Science Foundation Network (NSFNET) provided access tosupercomputer sites in the United States from research and education organizations, first at 56 kbit/s and later at 1.5 Mbit/s and 45 Mbit/s.[18] Commercial Internet service providers (ISPs) began to emerge in the late 1980s and early 1990s. The ARPANET was decommissioned in 1990. The Internet was commercialized in 1995 when NSFNET was decommissioned, removing the last restrictions on the use of the Internet to carry commercial traffic.[19] The Internet started a rapid expansion to Europe and Australia in the mid to late 1980s[20][21] and to Asia in the late 1980s and early 1990s.[22]

Since the mid-1990s the Internet has had a tremendous impact on culture and commerce, including the rise of near instant communication by email, instant messaging,Voice over Internet Protocol (VoIP) "phone calls", two-way interactive video calls, and the World Wide Web[23] with its discussion forums, blogs, social networking, and online shopping sites. Increasing amounts of data are transmitted at higher and higher speeds over fiber optic networks operating at 1-Gbit/s, 10-Gbit/s, or more.

The Internet continues to grow, driven by ever greater amounts of online information and knowledge, commerce, entertainment andsocial networking.[26] During the late 1990s, it was estimated that traffic on the public Internet grew by 100 percent per year, while the mean annual growth in the number of Internet users was thought to be between 20% and 50%.[27] This growth is often attributed to the lack of central administration, which allows organic growth of the network, as well as the non-proprietary open nature of the Internet protocols, which encourages vendor interoperability and prevents any one company from exerting too much control over the network.[28] As of 31 March 2011, the estimated total number ofInternet users was 2.095 billion (30.2% of world population).[29] It is estimated that in 1993 the Internet carried only 1% of the information flowing through two-way telecommunication, by 2000 this figure had grown to 51%, and by 2007 more than 97% of all telecommunicated information was carried over the Internet.[30]
