The Tour de France doesn't have a title sponsor, probably because it's prestigious enough that firms will pay large enough amounts to be associated with bits of it. The Milk Race OVO Energy Tour of Britain is smaller, so has more to gain from title sponsorship - the organisers have sold naming rights to the whole thing. Like the Rumbelow's Cup in football (or whatever it's called these days), Allianz Park in rugby or the Kia Oval.
