The nearest thing to any kind of advertising is the Fairy News Network carrying details of the latest exploits by Eileen, Hanastrew and so on during their broadcasts. Naturally the Queen and her Council wishes FNN would focus on the positive use of magic rather than also carrying details of the Witch's exploits and so on but the broadcasters insist they have to be balanced. Besides people should know what the Witch is up to as it gives folk a chance to get out of the way.
The Queen and her Council look with incredulity at our various forms of advertising. Eileen has got used to it since her defection to Earth but she still hates direct marketing and always will.
