A Google doodle is an artistic rendering of its logo on the search engine. Google uses it to celebrate different things including historical figures like Anton Wilhelm Amo, celebrated today, events like the Olympics, countries on their national day like Nigeria was celebrated on October 1 and holidays that run through the year in different parts of the world.
Many people get confused when they see a doodle, "has Google changed its logo?", they often ask. This is not the case, it is just an artistic way of celebrating people, places and things Google deems important.
