After startup of T-DMB and S-DMB in Korea, the total number of devices that has TDMB mobile tv feature has surpassed one million in Korea. TDMB mobile tv officially launched as the end of last year so it took approximately 6 months to sell one million devices. The number of mobile phones sold with TDMB so far was 324,092 and number of PMPs and TDMB USB devices for laptops sold was 681,816. The DMB optimized portable TV such as mobile phone and PDA or notebook not to use internet but do signal of satellites or broadcaster on earth.I expect this number to continue to grow rapidly as TDMB mobile tv feature will become a standard feature in a lot of the new mobile phones coming out this year and as most PMPs for car navigation is also being sold with TDMB. TDMB is attractive as there is no additional monthly fee for the service and no monthly network access fee.
