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 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 repost instagram content. 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 instagram posting content online with the hopes that it goes viral.
