The ten-hour video shown in this thumbnail is actually ten hours and 31 seconds long. Presumably, the extra half a minute is for the paid sponsorship. (thinking)

I fear that global warming could pose a real threat to the future of Fireplace 4K's channel. Perhaps an AirCon 4K channel could be worth a try? (shrug)
