Oh, that goes even further back, and includes names like "Diedre" (came from a soap opera, iirc), and even "Wendy" (Peter Pan). Hell, one could even talk about religions introducing new and trendy names into cultures. "Peter" (Petros) is one of those. In New Testament times, it was just a nickname - Rocky.
But I think the real metric would, again, be sticking power. Do those trendy names still get given to kids two, three, or more generations after the movie/book/TV show came out/was initially popular? Or are all the "Rainbows" and "Moon Units" bitter and restricted to one generation?
