Since its inception in 2001, Wikipedia has used different isologotypes. They all included a sphere written as a central form, symbolizing the world and knowledge. Since 2003, an incomplete sphere, known as a globo-rupture, was adopted as a central form in the logos, composed of pieces of a puzzle with graphics belonging to different world scriptures.

Each Wikipedia according to language is autonomous and has the power to choose the logo that identifies it. Since 2003 they have all adopted basically the same logo, with the expression Wikipedia the free encyclopedia ('Wikipedia la encyclopedia libre'), translated into the language in which each is written. The marking of various errors and inconsistencies in the symbols included in the globo-rupture, led to the design in 2010 of a new logo, coordinated in turn with a three-dimensional logo.

The logos have been made voluntary and free by Wikipedia users, and their copyright belongs to the Wikimedia Foundation.

First day logo
Wikipedia began as a project in English on 15 January 2001. The first image used was the American flag, placed by one of the initiators of the project, Jimbo Wales, in a precarious way and with no intention of assuming the project's logo status. However, the fact generated some criticism of ethnocentrism.

Nupedia Logo

Shortly after, the first Wikipedia logo, known as the Wiki Nupedia logo, was designed to mark the development of the project as an auxiliary tool for Nupedia. The author is in fact Bjørn Smestad. In March 2001, the logo was already installed, and was located in the right margin of the pages.

The logo is made by overlapping a phrase by English writer and mathematician Lewis Carroll over a circle, using the fish eye effect to simulate a sphere. The sphere is partially surrounded by two vertical black lines, difficult to interpret, which appeared as two slots in the sphere.

The phrase is a quote in English taken from Euclid and his Modern Rivals (Euclides and its modern rivals, Preface, p. X) by Lewis Carroll, which says:

The Cunctator

On November 20, 2001, Larry Sanger, co-founder of Wikipedia and editor-in-chief of Nupedia, proposed to the Wikipedia community in English to begin studying a replacement of the logo, also suggesting the inclusion of the word "Wikipedia" and, finally, the expression "free encyclopedia," always in English (The free encyclopedia).

On the same day, Magnus Manske made the first proposal: a square in blue and white, with the word "Wikipedia" on the top and the legend "The free encyclopedia" on the bottom, with an illegible text in the center, crossed by the phrase "You can edit this page right now!"
