As previously reported, Google was running a doodle for "Grimm's Fairy Tales" in parts of the world where Thursday came sooner than it does here in the U.S. Interestingly, now that the doodle has made its way to our neck of the woods, the query with which Google populates the search box, is "Brothers Grimm".
There do not appear to be any changes to the doodle itself, which is animated, and depicts the story of Little Red Riding Hood:
As I pointed out in a previous article, the "Grimm's Fairy Tales" doodle highlighted Grimm's Fairy Tales, and now we get to see Google's Knowledge Graph results for Jacob and Wilhelm Grimm, otherwise known as the Brothers Grimm. From Google's "Knowledge Panel" on the brothers (Wikipedia, really), we learn that they were German academics, linguists, cultural researchers, and authors who together collected folklore.
Google's Knowledge Graph is also good at recognizing the Terry Gilliam film The Brothers Grimm, which starred Heath Ledger and Matt Damon. A simple click, and the entire SERP changes to reflect the movie, showing the real power of the Knowledge Graph - helping searchers find what they're really looking for (even it if is inaccurate from time to time).
