Rice (1984) defined new media as communication technologies that enable or facilitate user to-user interactivity and interactivity between user and information.
1.2 Types of social media
According to many schorlars social media channels include a diversity of application with different core fiunction and structures ,for example social media channels today include facebook,myspace, linked in,and web blogs just to mention,therefore,there are many types of social media used for different functions; for instance social media for chatting,social media for sending videos e.t.c. Therefore social media have been classified by schorlars depending on their functions,based on this social media are classified into seven types.
There are seven types of social media ,the first type includes the wikis.according to Mayfield,2008;Pfeil,Zaphiris,&Ang,2006 wiki is a communication mechanism to create web based content that require allows its users to create ,modify and disseminate information,a good example of this social media is the wikipedia,another type of social media are web blogs, these according to John V.Pavlik 2013 are web pages of short, frequently update postings by an individual that are arranged chronologically,blogs contain thoughts ,links to sites of interest or whatever the blogger wants to write,a good example is word press.Another type of social media are discussions boards and web forums.John V.Pavlik 2013 describes it as ” a type of online “bulletin board” where internet users can post mesages that can be seen by others coming to the discussion board and in which they can post response to previous messages or posts or create their own discussions on a new topic,an example of this social media is the WELL(Whole earth ‘lectronic link).Another type of social media are socialnetworking sites, according toBoyd;Ellison,2007, they are sites that  enable users to articulate a network of connections of people with whom they wish to  share access to profile information, news, status updates, comments, photos, or other forms of content,example of such site is facebook.Another type of social media is the chat rooms,according to John V.Pavlik,2013 he describes chat room as “a virtual room”in which acommunity of users can visit and talk to each other through text messages in real time,an example of this social media is yahoo.another social media type are the microblogs.Microblogs according to John V.Pavlik,2013 is a technology that allows frequent update of shorter posts and content,an example in this is twitter.the last type of social media is email.John V.Pavlik describes it as an exchange of messages via telecommunication between two people.
1.3 General characteristics of social media
Mayfield ,2008 outlines the characteristic of social media into five: participation,openess,conversationality,community and connectedness.Participation according to Burgoon 2000,participation is the extent to which senders and receivers are actively engaged in in the interaction as opposed to giving monologues,passively observing or luking,its participatory nature allows interested parties an opportunity to engage in an interaction.For example encouraging conrtributions and feedback from everyone who is interested.Another characteristic of social media is openess.Openess according to Mayfield,2008 is defined by the perceived ease of giving and receiving information and comments by its media has few barriers that limits one to access information or make comments, so information can easily travel between sources and users(MeadowsKlue,2007).For example when we have the younger generation sharing information about their lives online via social media sites like facebook.Another characteristic of social media is connectedness,Teixeiria,(1992) describes connectedness as interpersonal ,community and general social ties.connectedness allows people to connect to the outside world and to easily expand their experiences.For example in facebook when we receive friend requests from friends or from friend of a friend.another characteristic of social media is conversationality,Mayfield ,(2008) describes it as the transmission or distribution of of information to an audiece by two way conversation rather than one direction.he gives his description with comparison to traditional media channels which was a one way communication mechanism or rather linear communication ,traditional media channels includes television,radio and newspaper just to mention.The last characteristic of social media is community and commonality, social media allows individuals and organizations to identify and communicate with the people whom they want to be associated with.(Mayfield, 2008) says it does so by offering a mechanism for individuals and organizations to form communities and to develop relationships effectively with others who share some commonality with them. For example, most social networking sites were launched to support demographics in an intimate, private community, such as the early Facebook for college students (Boyd ; Ellison, 2007). While social media helps foster communities, its aim is not simply on creating communities which are more continuous and regular in nature, and centered on a concept or common goal, as opposed to a collection of content. For example, viewers that post various online comments on a news story or video have something in common but might not necessarily be seen as belonging to a community. In other words, social media provides an effective means of developing communities, but its core utility is in linking individuals and organizations with others that share a certain commonality, as determined by their temporal needs and interests at the time of interaction.
1.4 The origin and history of social media
Six Degrees was the first social media site that was founded by a financial analyst and legal professional Andrew Weinreich, and was launched in 1997. Six Degrees was created based on the theory that every person in the world could be connected to each other by just six degrees of separation.

As the site grew, the world of online advertising was in its infancy and Weinreich was unable to keep the site afloat .Later after the closure of Six Degrees another founding father Adrian Scott came up with Ryze which was started in 2001,it was started to help connect business professionals .According to his book About Ryze,2013,”Ryze helps people make connections and grow their network.You can network to grow your business,build your career and life find a job and make sales,or just keep in touch with friends.”
