I mean, other modes of broadcast have latency too, just perhaps not quite as much. I'm not sure that, in itself, is an argument for keeping terrestrial. In theory, if all the BBC channels went iPlayer-only, there would be no perceptible lag because there'd be nothing else for it to be 'behind'

If you go to almost any streamer on Twitch you can get incredibly low latencies. One I'm watching at the minute shows a ~1.7 second latency (consistently between 1.6-1.8).
