According to the Verge they're already doing replays.

It's a little confusing because at WWDC Apple billed it as 24/7, and though they didn't actually use the word live I think that was the impression most people got. Who cares if it's 24/7 if 12 of the 24 hours are just replays of the previous 12 hours.
I rarely listen to local radio stations anymore. Do Clear Channel/iHeart Radio stations do replays during the day or middle of the night? How about BBC Radio stations?
