TV adverts going viral – Shetland Pony Dance – Silly Stuff. It Matters 
When advertisers intend for their ad to ‘go viral’, they place it online and encourage viewers to share it with their friends. These type of ads started as underground trends advertising cult products, but big brand advertisers now also take advantage of the potential market online. Viral ads need to be funny, cool, surprising or quirky in order for users to forward or share it. Advertisers also pay for slots on social networking sites and YouTube.
