Princess Caroline was featured in international magazines long before she was 17. Just check the thread on Caroline Cover Girl. She was 14 or less before the press knew they had a juicy subject there. Paris-Match, for all its faults, was one of her most ardent idols, always putting a nice twist on any fact or event that might appear negative. Granted, they do it to keep so there is no bad blood and she won't cut them off for future personal interviews, but they helped create a very favorable image of the princess.
I would slightly disagree with you. The absolutely positive for Caroline "Press instrument" was "Jours de France", presenting her like a perfect good studying girl who found the true love with Philippe Junot. Even where the "other press" was featuring Caro's pictures partying in Paris, "Jours de France" waw reporting that she was partying "once per year" after months of hard working at the University!
Paris Match was different, it was searching the scandal. Do not forget that it was Paris Match who discovered the affair of Caroline with Giullermo Villas, and they put cover with pictures of the couple, in a desert island.
Paris Match started to show a nice image of Caroline, after her mother's loss, and especially after wedding with Stefano, but this was unavoidable. First of all, it was not any scandal in her life, and secondly, this perfect image of a beautiful princess, a love marriage and three pretty kids, was selling!!! A gift! Caroline's life has always been a gold present for the press!
And do not forger the thousand of covers with Stephanie and hr lovers! When Stephanie supposed to be in happy couple with Paul Belmondo, it was Paris Match who first put her in cover with Anthony Delon, in a scandalueous suimsuit, etc etc.
The Monaco family has always been a golden gift for Paris Match, and this they knew it, despite the cost of "suits" they were selling more thant they were paying..
And now Paris Match reduced the coverage, just because Caroline getting older, and for ten years married with EA, is "less selling"!!!
