Do Sky show adverts during the Free Practice sessions? I was watching two of these elsewhere and as far as I know these were genuine Sky feeds complete with adverts. If not someone was being naughty and not telling me.
So you pay loads of money to watch adverts. Sounds like a good idea to Sky.
ITV Player now charges for most of their programmes now, both they and their freebies have adverts that you cannot fast forward through. Some (most?) of their adverts are interactive as well, whatever that means.
