That was with the network dominance of cadbury , marketing and it was also on the back of cartoons and books etc along with cult like collecting back in teh days of yoyos and footy cards . There wasn't teh internet etc.
We can't relive or compare the 90's as kinder has significant power and very good margin. There is a significant differentiation between the products and hopefully YOW and Kinder don't screw the market with a race to the bottom.
