Just because Koreans are able to watch TV on their mobile phone doesn't mean it's going to be an instant succes the world over. Let alone that operators will profit from it like some think they will.
"Techdirt believes that broadcast of TV to mobile phones is a lame duck, and hardly likely to be a big money earner. Delivery of custom, mobile-centric, short, affordable, video content (music videos, news and sports clips, very short films, animations...) has a chance of success in the short term, but this is very different than "TV". In 2 to 5 years, with increased storage abilities in handsets and home PVR use, some form of mobile PVR link will emerge, and that will be the key to bringing a winning TV-type product to mobile phones."
