I saw one with a friend from Turkey and we noted that it was common in both of our cultures. Is this because it is one of the oldest shared myths, of a result of cross contamination between cultures in more recent times?
The Folklore Thursday website recently picked up on this question. The site suggests a wide range of beliefs associated with meteors - which were seen in various culture in both positive and negative terms. This analysis suggests that there has been a modern inclination to see the positive side of a falling star and there is an implication that the international popularity of the 1940 Disney cartoon 'Pinocchio' may have spread the idea the one could 'wish upon a star', as its central song advocates. That sort of media-based diffusion of a belief and practice is not unknown; it seems a plausible explanation to me.
