Hyper Viral Marketing
Hyper Viral is a quality that a product or service has, if it’s very use, causes it to be virally marketed.
An example is Hotmail. At the bottom of every Hotmail email, is a message encouraging readers of the mail to go along to the hotmail website and sign up. If they do this, any email they send, will have the same message to anybody who reads it. Thus, Hotmail virally markets itself by its very use, without the need for Hotmail to instigate it.
