Us Westerners know that South Korea is ahead of us in terms of mobile technology, but we often assume that everything that’s launched there is successful, simply because it’s innovative. It appears that’s not always the case though, with DMB a prime example.

S-DMB (satellite) and T-DMB (terrestrial) have been available in Korea since 2005, but both have encountered problems which are less to do with the technology, and more to do with how they actually make money.
