Well back in 1999-2005, I was living in a different country (changing between Singapore-India) where we had F1 coverage on ESPN STAR, commentary by Steve Slater and Chris Goodwin from McLaren, awesome guys, and also sometimes by Alex Yoong and Karun Chandhok, and then also the same mix of on board cams like you mentioned (don’t remember how many, probably 4) were streamed, and that I’m sure was also used for Sky. So there is nothing exclusively for Sky. So to answer your question, I’d say shots selection is FOM, whoever be the ‘casters everybody sees the same thing.
Now, I live in Vienna, Austria and I’m paying for exclusive Sky feed, because I like their features and Croft/Ted/Brundle is unmatchable.. very cute Pinkham and former presenter Hottie Georgie were excellent too, but I digressed from the topic,
…well everybody, even ESPN STAR streams Sky’s stuff with Croft-Brundle-Ted commentary. But not Simon-Davidson part, that post-pre race show is their own. So in race you get same stuff, Sky doesn’t do anything special for you, FOM mixes everything.
If I’m wrong, please correct me.
PS- I don’t know anything about BBC, a channel that can’t find time to air Sherlock and delays it by half year, is no channel, in my books.
