> "Shows" can be easily cached on CDNs much closer to each consumer. "Live" can't. Um, no? You could argue that it isn't technically caching, and the system doing it isn't technically a CDN, but there's no reason why a broadcast can't be streamed to, say, 1000 SDN nodes, which each spool the stream in memory and serve it to 1000+ different recievers. A SDN node (server) is different infrastructure than a television station, so there might be issues with capital outlay, but I highly doubt it's more expensive once sunk costs are tallied.
