It astounds me how much US TV airtime is devoted to adverts - roughly 18 minutes out of every hour, AFAIK (plus any split-screen advertising shenanigans).
In the UK, (outside the BBC, which doesn't have adverts) TV broadcasters are limited to an overall average of 7 minutes per hour, with limits of 12 minutes for any individual clock hour (which drops to 8 minutes during primetime).
The BBC's Natural History unit deliberately inserts ten minutes of "disposable" content that can be cut from the program when it is broadcast on commercial channels (e.g. the 'Yellowstone People' segments that were included at the end of episodes of 'Yellowstone' when it was broadcast on the BBC, but are dropped when it's broadcast on commercial channels).
