BBC One’s live coverage from 06:00 to 09:15 averaged 1.74m (37.1%), up on last year’s 1.30m (30.5%) Sky Sports F1 averaged 494k (10.0%) from 06:00 to 09:30, up on last year’s 370k. BBC One’s repeat from 13:15 to 15:15 averaged 2.24m (21.3%), up on last year’s 1.92m (15.3%).
The BBC live programme peaked with 2.84m (33.6%) at 09:05, with Sky’s live coverage peaking with 776k (9.5%) at 08:50. 3.55m (42.0%) were watching BBC One and Sky Sports F1 at 09:05. BBC’s highlights peaked with 2.80m (25.1%) at 14:55.
Year-on-year, the combined number of 4.48m is up significantly on 3.58m in 2013 and is the most watched Japanese Grand Prix since at least 2006, and probably the last decade and a half. Same applies for the combined peak of 6.35m, which is the second highest peak of the entire year. Given the circumstances, those facts are not worth boasting about though, really.
