NBA - Talking, and sounding reasonabably smart, about most sports is hard. ESPN, and most other networks, have a few people that can do it, but it takes work and intellect. The number of people who can talk about more than one sport is quite small. Hence, the NBA obsession of its "embrase debate" talking heads. Talking about the NBA is simple. It is all just catch phrases, conclusory statements, and talk about feelings, emotions, and personalities which, if a female sport was covered in that way, would get every one fired.
4K - DirecTV does Notre Dame home games in 4K. It is OK, but it is not a world changer. In any event the capacity for more than a few 4K channels is years away. It is about where HD was in the late 90s or color was in the early 60s. Eventually it will probably be standard and then everybody is back to even.
Univision -Stories about the ratings for Spanish language networks beating English ones are all around. All ignore simple math. The English audience, though vastly larger, is split up 200 or 300 ways, while Spanish is, at best, split up 15 or so ways. In any event the Spanish networks are begining a slow, and inevitable, decline, as did non-English media forms in past generations. Remember the scene in The Godfather where Vito goes to the Italian play? Seen any Italian plays advertized lately? The grandkids and great-grandkids don't speak Italian. Same thing. Happened in every generation.
