A Google Doodle is a special, temporary alteration of the logo on Google's homepages intended to commemorate holidays, events, achievements, and historical figures. The first Google Doodle honored the 1998 edition of the long-running annual Burning Man event in Black Rock City, Nevada, and was designed by co-founders Larry Page and Sergey Brin to notify users of their absence in case the servers crashed. Early marketing employee Susan Wojcicki then spearheaded subsequent Doodles, including an alien landing on Google and additional custom logos for major holidays. Google Doodles were designed by an outside contractor, cartoonist Ian David Marsden until 2000, when Page and Brin asked public relations officer Dennis Hwang to design a logo for Bastille Day. Since then, a team of employees called Doodlers have organized and published the Doodles. Initially, Doodles were neither animated nor hyperlinked—they were simply images with tooltips describing the subject or expressing a holiday greeting. Doodles increased in both frequency and complexity by the beginning of the 2010s. On October 31, 2000, the first animated Doodle celebrated Halloween. On May 21, 2010, the first interactive Doodle appeared later celebrating Pac-Man, and hyperlinks also began to be added to Doodles, usually linking to a search results page for the subject of the Doodle. By 2014, Google had published over 2,000 regional and international Doodles throughout its homepages, often featuring guest artists, musicians, and personalities. By 2024, the Doodlers team had created over 5,000 Doodles for Google's homepages around the world.
