<P> Some social media sites have greater potential for content that is posted there to spread virally over social networks . This is an analogy to the concept of a viral infectious disease in biology, some of which can spread rapidly from an infected person to another person . In a social media context, content or websites that are "viral" (or which "go viral") are those with a greater likelihood that users will reshare content posted (by another user) to their social network, leading to further sharing . In some cases, posts containing controversial content (e.g., Kim Kardashian's nude photos that "broke the Internet" and crashed servers) or fast - breaking news have been rapidly shared and re-shared by huge numbers of users . Many social media sites provide specific functionality to help users reshare content--for example, Twitter's retweet button, Pinterest's pin function, Facebook's share option or Tumblr's reblog function . Businesses have a particular interest in viral marketing tactics because such a campaign can achieve widespread advertising coverage (particularly if the "viral" reposting itself makes the news) for a fraction of the cost of a traditional marketing campaign (e.g., billboard ads, television commercials, magazine ads, etc .). Nonprofit organizations and activists may have similar interests in posting content online with the hopes that it goes viral. social media websites are no longer performing an envisaged function of creating a positive communication link among friends, family and battleground, where insults fly from the human quiver, damaging lives, destroying self - esteem and person's sense of self - worth . </P> <P> Mobile social media refers to the use of social media on mobile devices such as smartphones and tablet computers . This is a group of mobile marketing applications that allow the creation, exchange, and circulation of user - generated content . Due to the fact that mobile social media run on mobile devices, they differ from traditional social media by incorporating new factors such as the current location of the user (location - sensitivity) or the time delay between sending and receiving messages (time - sensitivity). According to Andreas Kaplan, mobile social media applications can be differentiated among four types: </P> <Ol> <Li> Space - timers (location and time sensitive): Exchange of messages with relevance mostly for one specific location at one specific point in time (e.g. Facebook Places What's app; Foursquare) </Li> <Li> Space - locators (only location sensitive): Exchange of messages, with relevance for one specific location, which is tagged to a certain place and read later by others (e.g. Yelp; Qype, Tumblr, Fishbrain) </Li> <Li> Quick - timers (only time sensitive): Transfer of traditional social media applications to mobile devices to increase immediacy (e.g. posting Twitter messages or Facebook status updates) </Li> <Li> Slow - timers (neither location nor time sensitive): Transfer of traditional social media applications to mobile devices (e.g. watching a YouTube video or reading / editing a Wikipedia article) </Li> </Ol> <Li> Space - timers (location and time sensitive): Exchange of messages with relevance mostly for one specific location at one specific point in time (e.g. Facebook Places What's app; Foursquare) </Li>
