The credentials of the filmmakers, the size of the production, a high-profile marketing campaign and a primetime BBC One timeslot all resulted in Planet Earth attracting large audiences when it debuted in the UK in March 2006. The first episode, "From Pole to Pole", was watched by more people than any natural history programme since Attenborough and Fothergill's previous series, The Blue Planet, in 2001. The first five episodes drew an average audience of 11.4 million viewers, including the early evening repeats, outperforming even The Blue Planet. When the series returned to British screens after a six-month break, it remained popular but viewing figures did not reach the same levels. The final six episodes attracted an average audience of 6.8 million viewers, appreciably lower than the spring episodes, but still higher than BBC One's average for the timeslot. The BBC's 2007 Annual Report revealed that the series "received the highest audience appreciation score of any British programme on TV this year". In the United States, Planet Earth drew equally impressive ratings when it premiered on Discovery and Discovery HD Theater on 25 March 2007. The first three episodes (screened back to back) averaged 5.72 million viewers with a peak of 6.07 million viewers, giving the network its third highest audience ever. It was also the most watched Discovery programme since The Flight That Fought Back in 2005.
