A social network service focuses on the building and verifying of online social networks for communities of people who share interests and activities, or who are interested in exploring the interests and activities of others, and which necessitates the use of software.

Most social network services are primarily web based and provide a collection of various ways for users to interact, such as chat, messaging, email, video, voice chat, file sharing, blogging, discussion groups, and so on.

The main types of social networking service are the Old School Tie which is akin to a directory of former classmates, the Web of Contacts, which is a technology that builds networks based on the six degrees of separation principle (Brown, 1998)^[1], and the Circle of Friends, which is now the most popular method as it allows users to manage their social networks (NWT, 2007)^[2]. There are newer methods, which combine some of these more established techniques, such as the such as the Web of Friends used by Friendster^{[citation needed]}.

There have been some attempts to standardize them (see the FOAF standard) but this has led to some privacy concerns.

The notion that individual computers linked electronically could form the basis of computer mediated social interaction and networking was suggested early on – for example The IRG Solution by David Andrews^[3] – effectively sketched out the Internet and how it should be developed specifically for this purpose.

The notion that individual computers linked electronically could form the basis of computer mediated social interaction and networking was suggested early on - for example The Network Nation by S. Roxanne Hiltz and Murray Turoff (Addison-Wesley, 1978, 1993) effectively sketched out how computer-mediated communication -- such as the Internet -- should be developed for this purpose.

There were many early efforts to support social networks via computer-mediated communication, including Usenet, bulletin board services (BBS), Arpanet, and EIES: Murray Turoff's Electronic Information Exchange Service (Turoff and Hiltz, 1978, 1993).

Early social networking websites include Classmates.com 1995, focusing on ties with former school mates using the Old School Tie social networking method, and SixDegrees.com, 1997, focusing on indirect ties using the Web of Contacts. Two different models of social networking that came about in 1999 were the Circle of Trust developed by Epinions.com and the Circle of Friends developed by Jonathan Bishop, the later of which which was utilized on a number of regional UK sites between 1999 and 2001 before being adopted by Friendster in 2002 according to NWT (2007), perhaps because it gives the user more control over content and connectivity than the earlier Web of Contacts model. By 2005, one social networking service using the Circle of Friends, MySpace, was reportedly getting more page views than Google, with Facebook, a competitor rapidly growing in size also using the Circle of Friends^[4]. In 2007, Facebook began allowing externally-developed add-on applications, and some applications enabled the graphing of a user's own social network -- thus linking social networks and social networking.

Social networking began to be seen as a component of business internet strategy at around March 2005 when Yahoo launched Yahoo! 360° and in July 2005 News Corporation bought Circle of Friends-based MySpace, followed by ITV buying Old School Tie-based Friends Reunited in December 2005.^[5][6] It is estimated that combined there are now over 200 social networking sites using these existing and emerging social networking models.

Social networks connect people at low cost; this can be beneficial for entrepreneurs and small businesses looking to expand their contact base. These networks often act as a customer relationship management tool for companies selling products and services. Companies can also use social networks for advertising in the form of banners and text ads. Since businesses operate globally, social networks can make it easier to keep in touch with contacts around the world. In many ways business networking on social networks has eclipsed the amount of networking that takes place on dedicated business networking websites.

Social networks are beginning to be adopted by healthcare professionals as a means to manage institutional knowledge, disseminate peer to peer knowledge and to highlight individual physicians and institutions. The advantage of using a dedicated medical social networking site is that all the members are screened against the state licensing board list of practitioners.^[7]

The role of social networks is especially of interest to pharmaceutical companies who spend approximately "32 percent of their marketing dollars" attempting to influence the opinion leaders of social networks.^[8]

In general, social networking services, such as MySpace, Facebook and Bebo, allow users to create a profile for themselves. Users can upload a picture of themselves and can often be "friends" with other users. In most social networking services, both users must confirm that they are friends before they are linked. For example, if Alice lists Bob as a friend, then Bob would have to approve Alice's friend request before they are listed as friends. Some social networking sites have a "favorites" feature that does not need approval from the other user. Social networks usually have privacy controls that allows the user to choose who can view their profile or contact them, etc.

Some social networks have additional features, such as the ability to create groups that share common interests or affiliations, upload videos, and hold discussions in forums. Geosocial networking co-opts internet mapping services to organize user participation around geographic features and their attributes.

Currently, almost no social networks charge money for membership. In part, this may be because social networking is a relatively new service, and the value of using them has not been firmly established in customers' minds.^[9] Instead, companies like MySpace and Facebook sell online advertising on their site.^[10][11] Some believe that the deeper information that the sites have on each user will allow much better targeted advertising than any other site can currently provide.^[12] Sites are also seeking other ways to make money, such as by creating an online marketplace (Facebook's Marketplace)^[13] or by selling professional information and social connections to businesses (LinkedIn).^[14]

Business networking sites have absorbed the traditional face-to-face referral networking practices of realtors and title companies, attorneys and chiropractors, and businesses networkers from a variety of fields, and taken it online. Businesses from all across the globe can come together and share ideas, clients, and referrals in a mutually beneficial manner. Such sites allow users to network with one another online, without ever having to meet someone face-to-face. Some of these services are entirely free.

In addition to internet-based social networking, cell phone manufacturers are getting into the social networking business with phones that allow users to create lists of friends and associates, track their movements even across countries, and create customized maps and alerts that signal the user when a desired person is within a predetermined range. With such GPS-enabled phones, users are able to send out invitations or messages to groups of people based on customized attributes, including location.^[15]

Users often try to "collect friends", or try to be linked to as many friends as possible. Therefore, it is not uncommon for users to receive friend requests from people that they do not know. Some users will create additional profiles that assume the identity of someone else, such as celebrities, politicians, or even their pets. Some will create profiles for fictional characters, such as those from video games or films (similar to role-playing), and some will even create profiles for inanimate objects, such as the Sun or the dwarf planet Pluto.

On large social networking services, there have been growing concerns about users giving out too much personal information and the threat of sexual predators. Users of these services need to be aware of data theft or viruses. However, large services, such as MySpace, often work with law enforcement to try to prevent such incidents.

In addition, there is a perceived privacy threat in relation to placing too much personal information in the hands of large corporations or governmental bodies, allowing a profile to be produced on an individual's behavior on which decisions, detrimental to an individual, may be taken.

Furthermore, there is an issue over the control of data - information having been altered or removed by the user may in fact be retained and/or passed to 3rd parties.

Social network services are increasingly being used in legal and criminal investigations. Information posted on sites such as MySpace and Facebook, has been used by police and university officials to prosecute users of said sites. In some situations, content posted on MySpace has been used in court to determine an appropriate sentence based on a defendant's attitude.

Facebook is increasingly being used by school administrations and law enforcement agencies as a source of evidence against student users. The site, the number one online destination for college students, allows users to create profile pages with personal details. These pages can be viewed by other registered users from the same school which often include resident assistants and campus police who have signed-up for the service.
