Netflix seems to be really leading the charge on this 4K thing. CEO Reed Hastings just took the stage at Sony's CES presser and said that all of its future original content will be shot in ultra high-def. That's a whole lotta pixels.
It's also worth pointing out that it's not the first time Hastings has been around the show touting 4K on Netflix today. This morning he made an appearance at LG's press conference to talk 4K support for Netflix on LG TVs. Liked House of Cards? Kevin Spacey is probably even more sinister in 4K.
