South Korean communications provider KT will stop investing in its fixed-line telephony services as mobile and internet communications are growing. The company will instead focus on smartphones and other mobile internet devices, the Korea Times reports. Seo Yu-yeol, head of KT's home customers division, said there was "no future" in fixed-line telephony services. "In just over a year, KT added 10 million smartphone customers and I think that's very inspiring. Fixed-line voice services have been KT's bread-and-butter business for a long period and have contributed greatly to the nation's economic development. However, it's clearly a thing of the past," Seo said.
