What term describes the process where a particular content item becomes widely popular through sharing?

The term that describes the process where a particular content item becomes widely popular through sharing is "viral." This concept originates from the way viral infections spread rapidly from person to person, drawing a parallel to how content can be disseminated across social networks rapidly and widely as users share it with their connections.

When content is labeled as viral, it indicates that it has reached a significant audience in a remarkably short time, often because it resonates well with viewers or has compelling qualities that prompt sharing. The viral effect is often bolstered by various factors, such as humor, emotional appeal, or relatable themes that encourage users to share with their own networks, thereby amplifying its reach exponentially.

The other terms, while related to popularity in the digital context, do not specifically encapsulate the idea of rapid spreading through sharing. "Trending" refers to content that is currently popular or gaining attention at a specific moment but does not necessarily imply the extensive spread characteristic of viral content. "Popular" describes something that is widely liked or accepted but lacks the dynamic aspect of sharing. "Buzz" refers to the excitement or discussion surrounding a topic but does not denote the process of content sharing itself.
