Occasionally, Google add what they call a ‘doodle‘ to their search engine home page to commemorate a historical or current even, someone’s birthday, or other historical occasion. Every day, there could be 100’s of different things that they could acknowledge. Given that there are 100’s there is always going to be someone who is not happy that “their” favorite event was not acknowledged. They often turn up at Google groups whinging about it. They need to get over it.
