Aman adds a video file to his social networking page. Which one of these describes a video that has been watched by a lot of people over a short period of time?

A video watched by very many people in a short span is described as having gone viral.

Digital merely means the content is in electronic form and says nothing about its popularity.

Tagged means the video has labels or people marked in it, again unrelated to how many watch it.

Open source refers to freely shareable source code, which does not describe a video's spread.

Viral spread happens as viewers rapidly share the video onward across their own networks.

The name draws on how a virus multiplies quickly from person to person.
