4K/UHD resolution TVs are soon heading away from being solely the preserve of the hardcore enthusiast-- according to Statista global 4K TV shipments are to grow from 900000 in 2013 to a 48.1 million in 2016.
Such numbers show 4K TV penetration breaking past 20% this year. This is an impressive achievement, considering penetration was hardly above 0% just 3 years ago.
However the analyst warns the near future might bring a threat to 4K TV-- after all, just as HDTV is about to get beaten by its higher resolution brother, one can easily assume something similar will happen once 8K TV (something already in development) goes commercial.
