Google has had several logos since its renaming from BackRub. The current official Google logo was designed by Ruth Kedar, and is a wordmark based on the Catull typeface. The company also includes various modifications and/or humorous features, such as cartoon modifications of their logo for use on holidays, birthdays of famous people, and major events, such as the Olympics. These special logos, some designed by Dennis Hwang, have become known as Google Doodles. Google subsidiary YouTube has also featured some custom logos to highlight special events occurring on the site, these have been unofficially nicknamed "Yoodles".

In 1998, Sergey Brin created a computerized version of the Google letters using the free graphics program GIMP. The exclamation mark was added, mimicking the Yahoo! logo. "There were a lot of different color iterations", says Ruth Kedar, the graphic designer who developed the now-famous logo. "We ended up with the primary colors, but instead of having the pattern go in order, we put a secondary color on the L, which brought back the idea that Google doesn't follow the rules."

Arthur "Art" Clokey (October 12, 1921 – January 8, 2010) was an American pioneer in the popularization of stop motion clay animation, beginning in 1955 with a film experiment called Gumbasia, influenced by his professor, Slavko Vorkapich, at the University of Southern California.

After the Gumbasia project, Art Clokey and his wife Ruth came up with the clay character Gumby. Gumby and his horse Pokey became a familiar presence on American television; they had their start in the Howdy Doody Show, and later got their own series The Adventures of Gumby. The characters enjoyed a renewal of interest in the 1980s when American actor and comedian Eddie Murphy parodied Gumby in a skit on Saturday Night Live. In the 1990s Gumby: The Movie was released, sparking even more interest.

Clokey's second most famous production is the duo of Davey and Goliath, funded by the Lutheran Church in America.

Clokey was born Arthur Charles Farrington in Detroit, Michigan. When he was nine years old, his parents divorced and he stayed with his father, Charles Farrington. After his father died in a car accident, he went to live with his mother in California, but his stepfather had no interest in raising another man's son, and so Arthur was sent to an orphanage. When he was 11 or 12, he was adopted by Joseph W. Clokey, a classical music composer and organist who taught music at Pomona College in Claremont, California. He schooled Arthur in painting, drawing, and film making while also taking him on journeys to Canada and Mexico. The aesthetic environment later became the home of Clokey's most famous character, Gumby, whose name derives from his childhood experiences during summer visits to his grandfather's farm, when he enjoyed playing with the clay and mud mixture called "gumbo".

Freddie Mercury (born Farrokh Bulsara (Gujarati: ફારોખ બલ્સારા‌), 5 September 1946 – 24 November 1991) was a British musician, singer and songwriter, best known as the lead vocalist and lyricist of the rock band Queen. As a performer, he was known for his flamboyant stage persona and powerful vocals over a four-octave range. As a songwriter, Mercury composed many hits for Queen, including "Bohemian Rhapsody", "Killer Queen", "Somebody to Love", "Don't Stop Me Now", "Crazy Little Thing Called Love" and "We Are the Champions". In addition to his work with Queen, he led a solo career, and also occasionally served as a producer and guest musician (piano or vocals) for other artists. He died of bronchopneumonia brought on by AIDS on 24 November 1991, only one day after publicly acknowledging he had the disease.

Mercury was a Parsi born in Zanzibar and grew up there and in India until his mid-teens. He has been referred to as "Britain's first Asian rock star". In 2002, Mercury was placed at number 58 in the BBC's poll of the 100 Greatest Britons, in 2006, Time Asia named him one of the most influential Asian heroes of the past 60 years, and he continues to be voted one of the greatest singers in the history of popular music. In 2005, a poll organised by Blender and MTV2 saw Mercury voted the greatest male singer of all time. In 2008, Rolling Stone editors ranked him number 18 on their list of the 100 greatest singers of all time. In 2009, a Classic Rock poll saw him voted the greatest rock singer of all time.Allmusic has characterised Mercury as "one of rock's greatest all-time entertainers", who possessed "one of the greatest voices in all of music".

Saul Bass (May 8, 1920 – April 25, 1996) was a graphic designer and filmmaker, perhaps best known for his design of film posters and motion picture title sequences.

During his 40-year career Bass worked for some of Hollywood's greatest filmmakers, including Alfred Hitchcock, Otto Preminger, Billy Wilder, Stanley Kubrick and Martin Scorsese. Amongst his most famous title sequences are the animated paper cut-out of a heroin addict's arm for Preminger's The Man with the Golden Arm, the credits racing up and down what eventually becomes a high-angle shot of the United Nations building in Hitchcock's North by Northwest, and the disjointed text that races together and apart in Psycho.

Bass designed some of the most iconic corporate logos in North America, including the AT&T "bell" logo in 1969, as well as AT&T's "globe" logo in 1983 after the breakup of the Bell System. He also designed Continental Airlines' 1968 "jetstream" logo and United Airlines' 1974 "tulip" logo which became some of the most recognized airline industry logos of the era.

Sir Charles Spencer "Charlie" Chaplin, KBE (16 April 1889 – 25 December 1977) was an English comic actor, film director and composer best known for his work during the silent film era. He became the most famous film star in the world before the end of World War I. Chaplin used mime, slapstick and other visual comedy routines, and continued well into the era of the talkies, though his films decreased in frequency from the end of the 1920s. His most famous role was that of The Tramp, which he first played in the Keystone comedy Kid Auto Races at Venice in 1914. From the April 1914 one-reeler Twenty Minutes of Love onwards he was writing and directing most of his films, by 1916 he was also producing them, and from 1918 he was even composing the music for them. With Mary Pickford, Douglas Fairbanks and D. W. Griffith, he co-founded United Artists in 1919.

Chaplin was one of the most creative and influential personalities of the silent-film era. He was influenced by his predecessor, the French silent film comedian Max Linder, to whom he dedicated one of his films. His working life in entertainment spanned over 75 years, from the Victorian stage and the music hall in the United Kingdom as a child performer, until close to his death at the age of 88. His high-profile public and private life encompassed both adulation and controversy. Chaplin was identified with left-wing politics during the McCarthy era and he was ultimately forced to resettle in Europe from 1952.
