As far as I know, fat_jez is correct.
Bernie at some point in the past assumed the role and gradually took ownership of the commercial rights.
Without any person, team or group seemingly voicing any objection or concern.
He subsequently sold what he had to CVC and is now employed by them.
It's quite incredible really when you think about it.
Bernie takes something which he doesn't own and becomes exceedingly rich from the work and expenditure of others (circuit owners, teams, sponsors, etc.).
I can't think of any other instance in history where something like this has happened.
