How much is a kilo of Buzz?

Buzz marketing is clearly a victim of its success, but what a-buzz? It seems a recipe buzz is starting to take shape (good or not) over the operations. I have not identified the last operations of buzz on the web but I can say without too much risk there are dozens every month.

What is this famous recipe? I call it the american dream Full package, ie the operation that will make the dream client. Currently, the client wants to impress visitors to see, he hears about everything (anything); between virtual worlds, blogs, community networks, buzz marketing, advergames and viral videos, it does not really know where to turn. So when an agency is advanced and offers her a prez 'which offers a mix of all these new channels of communication ultra trends, the client is in heaven ...

Making Buzz Marketing for a company is like buying a car from a dealer, we choose the options according to the budget ...

Take for example last season Casio GShock conducted by agency Chewing Com. I loved their campaign for Orangina (Pulpeuse) but then, I am not at all attractive.

Buzz Package:

1. 3 spots so crazy viral Jackass
2. A page Dailymotion branded GShock
3. A mini site with Flash and mechanical Advergame Viral

As a blogger and tired accustomed to this type of operation (very original) I claim a share what are the benefits and ROI (hardly measurable) but also how much is charged for such operation. Leave the professional standards of that buzz?
