Usage of TV mobile in European countries and South Korea

We are interested to know the usage of TV in the mobile in European countries, South Korea and others. We need more specific information such as number of actors offering the service, how many people are using it, demographic distribution of users, etc. We would also like to have similar information for a second country for comparative purposes, preferably a country that has launched the service but does not necessarily need to be as advanced as South Korea. Prominent research services like KPO or BPO who can provide this service to us within 30 days time will be highly appreciated. Thank you. Anees Ahmed
