South Koreans want their sub-TV

Reeling from declining ad revenue and mounting debt from providing the expensive service at no additional cost to subscribers, South Korean cellular operators may soon cancel subway TV coverage that has yet to turn a profit. Losing underground TV reception may not seem like much to consumers in the U.S., where many are still struggling with cellular dead zones and where a switch to full above-ground digital TV service may leave millions staring at useless analog sets. But for many South Koreans, subway TV has become a familiar part of their daily routines. Phone companies in this digitally crazed nation in 2005 were the first to launch mobile TV that could be tuned in on phones just about anywhere -- even in the subway tunnels deep beneath Seoul and other cities. Today, nearly 10 million cellular users are watching soap operas, sports and sitcoms on a special frequency dedicated to portable viewing -- enjoying it all on larger digital-quality screens and high-tech handsets to improve reception.
