South Korea’s Samsung Electronics has launched a range of giant Internet-enabled televisions as part of a strategy to cement its lead in slowing global markets by focusing on premium models. The 16 new “smart TV” models, which come in sizes ranging from 46 to 75 inches, allow users to navigate the Internet, offer specialized apps such as video games and recognise various spoken queries and hand motions. Questions such as “What’s today’s TV schedule for football matches?” or “Any action films scheduled on TV this weekend?” will result in a list of requested TV programmes. They also zoom in and out, or rotate images on screen as well as change channels by recognising certain hand motions. The firm said the new models would hit South Korean stores on Saturday but did not say when overseas sales would start. One 55-inch model is priced at nearly 6.0 million won ($5,550).
