why else would they sponsor it?
Whatever else you say about Sky they have put more money into cycling in the last few years than anyone else.
How much coverage did it used to get by anyone else.
Personally I see the BBC as bandwagon jumpers - totally disinterested until someone else has made the investment and done all the hard work
Are you kidding? Eurosport have much, much more coverage of cycling than Sky and have been doing so for years.
Apart from the TdU I can't think of any other races Sky cover.
