This somewhat queer campaign enables the user to win a CR-Z by mereley changing one's nickname within mixi, Japan's largest social networking service, which the core user mostly consistes 20s and 30s (an estimated body of users is more than 10,000,000). Not only changing your own, if the participant can convince their friends to change their nicknames, the probablity of winning the prize gets added on. The users actively engaged with this campaign by utilising the 'invite' feature, and started asking friends to add CR-Z to their nicknames.

In a while, mixi was filled with CR-Z and more than 800,000 users have added CR-Z to their nicknames. The total number of users within mixi is 16,000,000. With a number of 800,000 people taking part in this campaign, it means that at least 1 friend out 20 has CR-Znised. The campaign created a situation such that, anyone using mixi will encounter the name CR-Z. The number of orders for CR-Z was 10,000, which was 10 times more than the expected number. 50% of the people who purchased were in their 20s and 30s, which was also against the expectation.
