Viral content is any piece of media that suddenly becomes an online sensation. You have almost certainly seen this happen -- that indelible image or outrageous video that gets forwarded to you by a dozen friends in under an hour. The democratic structure of the Web has made this sort of thing commonplace nowadays, as a single text, tweet, status update, or link is all it takes to "gift" something amazing to everyone you know.
Not all great content goes viral, but (with the exception of awesomely terrible videos) content that does go viral is great. No one can guarantee that any piece of content will take the web by storm, but we can make sure that a piece of content has what it takes.
Would love to hear your feedback on it. I'd especially love to see if anyone has done well with viral content in the past.
