Also, in many races (spring classics, Giro Rosa), there are TV cameras capturing the action. Since it supposedly does not make sponsors money, why isn't the footage freely available? The UCI should release the complete footage of the spring classics, which it owns, instead of 10 min of often poorly edited videos. They could get a sense of potential viewership. Personally, I'd pay to see better coverage of the Giro Rosa or the Tour of Britain, much like I pay to see the TdF.
Anyway, more exposure should lead to better sponsorship for teams and a deeper field.
