Very cool. One interesting detail is that the phenomenon spikes right around the time it's named. I hadn't heard the name before (and don't actually like it). But it makes sense that the successful introduction of a name would coincide with exponential growth in the thing being named.
I looked through the author's list to see whether it includes the immortal zombo.com (it does), and scanned through it for other really old instances. There are a few from the 90s, the best of which is the oldest (1996) - perdu.com, which made me laugh. It's in French, though. (I started typing out a translation but it felt like spoiling the joke.)
