Evidence? Renault did a scheme some years back where they tried to encourage young/new engineers into F1 by offering the one(s) with the most potential from the likes of colleges and universities a place in Renaults engineer team.
tbh i always like it on bbc. it has no adverts, brilliant commentators and if the race is delay ( like Canada ) the F1 gets priority over the antiques roadshow. i see no reason or a benefit of Sky taking over.
