Internet users who prefer the Google search engine have long noticed that the company's logo changes on holidays and memorable dates. These changes to the design of the lettering are called the Google Doodle, which can be translated as "Google drawing".
The first Google Doodle image appeared on the Internet in 1998. It was dedicated to the Burning Man Festival, which is held annually in northern Nevada. The next themed logo appeared in 2000 in honor of Bastille Day. In the following years, Google Doodle was regularly used across all regional search engine domains.
Most often, the Google logo change is timed to coincide with the birthday of prominent scientists and cultural figures. Doodle drawings reflect the work of Leonardo da Vinci, Albert Einstein, Andy Warhol, Nikola Tesla, Antonio Vivaldi, John Lennon and many others. A special logo design celebrates not only the anniversaries of prominent personalities, but also individual companies, for example, on the fiftieth anniversary of Lego, the Google inscription was created from parts of the eponymous constructor. Other Google Doodle themes are historical events, religious and public holidays, and all kinds of festivals.
In the Russian domain of the search engine, the most striking logos from the Google Doodle series in 2011 were dedicated to the 450th anniversary of St. Basil's Cathedral, the 100th anniversary of the A. S. Pushkin, Day of Russia, Day of Knowledge. Thematic designs of the inscription also marked the anniversaries of great Russians: the 190th anniversary of the birth of F. M. Dostoevsky, 300th anniversary of M. V. Lomonosov, 90th anniversary of Yu. V. Nikulin and others.
Of particular interest to users are animated (moving) and interactive logos. So, on Halloween 2011, the company showed a doodle in the form of accelerated shooting, in which its employees cut out a logo from pumpkins. Interactive logos can be interacted with by hovering the mouse cursor over them. The user is invited to play virtual guitar strings, play a mini-game or solve a puzzle.
