Wonder how Dish Networks stock has done? They've been hemorrhaging subscribers, but have led the pack with Sling TV. (I've done zero research.) You are probably too late on roku; they are a big market leader on this. Those are of the two most impressive innovators I've seen. I also continue to be shocked that Tablo is not more popular; not sure who owns them, but they crush other OTA DVR for functionality and actually not hard to use.
