4k Content on Youtube

I have always been an audio guy. I could have cared less about a big tv or projector or whatever. I might even have mentioned this in previous posts. I think when I got married a little switch was flipped cause now I want it all. Further more I want the lasted and greatest. I love 4k quality. It is becoming more prevalant and popular. More content is coming around for it as well. Including on the web. Places like Youtube are starting to have 4k content. It really would not suprise me if that became the first big place for 4k. I have included a video above shot in 4k, pretty sure with RED Camera technology by Sony.
