A viral phenomenon is a term associated with a piece of content that becomes incredibly popular in a short period of time through online sharing. The concept was first proposed by Richard Dawkins in 1976 when he introduced the term ‘meme’ to describe how ideas spread. The phenomenon is likened to a virus due to its rapid and extensive spread across the internet[3], impacting human behavior, societal trends, and even shaping public discourse[2]. The content could take various forms, such as videos, images, or text and is primarily driven by social networks, platforms like YouTube[4] and TikTok[5], and user behaviors. It’s also significant in the marketing world as brands leverage it for exposure and reach. However, the rapid spread also poses ethical issues, including the spread of disinformation[1] and privacy[6] concerns.
Viral phenomena or viral sensation are objects or patterns that are able to replicate themselves or convert other objects into copies of themselves when these objects are exposed to them. Analogous to the way in which viruses propagate, the term viral pertains to a video, image, or written content spreading to numerous online users within a short time period. This concept has become a common way to describe how thoughts, information, and trends move into and through a human population.
The popularity of viral media has been fueled by the rapid rise of social network sites, wherein audiences—who are metaphorically described as experiencing "infection" and "contamination"—play as passive carriers rather than an active role to 'spread' content, making such content "go viral". The term viral media differs from spreadable media as the latter refers to the potential of content to become viral. Memes are one known example of informational viral patterns.
