Google releases its review of the year, looking at the trends in searches. In the top gainers of the year, there are 2 cultural references which stand out from the other web/media terms. The first is Leonardo de Vinci, I’m guessing driven from the Dan Bown book and the Spielberg film. The other is Green Day – of course, the increases interest in that band could not have been driven from the mashup album American Edit 😉
They’ve picked a number of different items to highligh… just look at the increase in searches for wiki.
