To be honest, credits goes to all rippers throughout the years, for giving people like me in Hong Kong and others in Far East to enjoy the most up-to-date coverage of latest TG/ FG shows.
Some years ago I did woke up early in the morning (=GMT late night), staying in front of the PC and wait for the release of the torrent, those were the days.
There was some motivations towards BBC overseas pay-channel and local TV stations regarding the popularity of torrents.
Before 2012, at least half-year-delay for BBC Knowledge to show the latest season, not to mention a year delay for the local TV's English channels.
Starting from 2014, BBC Knowledge had managed to get a 3-week-delay of the latest episode, with Chinese subtitles ready (yes, for HK & Taiwan markets).
This is the power of competition. Still, I would have those beautiful 1080i files on my PC, because they are just awesome.
