I'm afraid that's nonsense. Nothing much has been talked about Sky's viewership, or how the Sky coverage is being packaged for others around the world. That will transpire over the course of this year.
Ecclestone is trying to put a brave face on it by talking about Sky's 10 million households, but he's just trying to paint over what he knows is true - you're going to get a far smaller proportion of the total. Sky's coverage of the Chinese GP peaked at less than a million at 887,000, and that is only going to go down and fluctuate over the course of the season. The BBC's coverage was 4.21 million for the same live race, down a million on last year as to be expected really. The coverage just hasn't helped, there isn't any momentum with them not showing all the races live and Sky aren't even making up the losses. There is just no contest.
Basically, everyone has been hurt by this and the momentum built up over the past few years of the BBC building up the viewership for Formula 1 been seriously eroded, if not lost. It makes no sense for Formula 1 because unlike football they are not being funded by Sky subscriptions.
