Consumer behaviors in Ubiquitous Emotional Society
Tailored consumption that increases the value of individuals!
- Personalization & individualization- Self-Customization
Customers Want What ?
•1 Taste to 10 persons
• price competition• brand competition• reasonable consumer• clever consumer
•10 Tastes to 1 person
• value competition• personality competition• emotional consumer• profit-making prosumer

New Communication Needs in U-society
Communication of Emotion & Sensibility
Then, Next Communication is?
Monthly communication expenditure; $130/household;
(average expenditure of America, England, German, $65/household)Portion of total expenditure; 6.5%
(3 times of OECD countries)12 million of Internet users 38 million of mobile phone users
Communication that enablesto increase productivityto make a variety of cultural exchange to express oneselfto make self-customized service
Increasing demand forHigh-quality multimediaMobileInteractive peer-to-peerDistribution of self-generating content
New trend of communication
New needs for value communication
Communication demand saturated in Korea
