Wikipedia (ⁱ/ˌwɪkɨˈpiːdiə/ or ⁱ/ˌwɪkiˈpiːdiə/ WIK-i-PEE-dee-ə) is a free, collaboratively edited and multilingual Internet encyclopedia supported by the non-profit Wikimedia Foundation. Its 22 million articles (over 0 million in English alone) have been written collaboratively by volunteers around the world. Almost all of its articles can be edited by anyone with access to the site, and it has about 100,000 regularly active contributors. As of June 2012, there are editions of Wikipedia in 285 languages. It has become the largest and most popular general reference work on the Internet, ranking sixth globally among all websites on Alexa and having an estimated 365 million readers worldwide. It is estimated that Wikipedia receives 2.7 billion monthly pageviews from the United States alone.

Wikipedia was launched in January 2001 by Jimmy Wales and Larry Sanger. Sanger coined the name Wikipedia, which is a portmanteau of wiki (a type of collaborative website, from the Hawaiian word wiki, meaning "quick") and encyclopedia. Wikipedia's departure from the expert-driven style of encyclopedia building and the presence of a large body of unacademic content have received extensive attention in print media. In its 2006 Person of the Year article, Time magazine recognized the rapid growth of online collaboration and interaction by millions of people around the world. It cited Wikipedia as an example, in addition to YouTube, MySpace, and Facebook. Wikipedia has also been praised as a news source because of how quickly articles about recent events appear. Students have been assigned to write Wikipedia articles as an exercise in clearly and succinctly explaining difficult concepts to an uninitiated audience.

Natalie Hershlag (Hebrew: נטלי הרשלג‎; born June 9, 1981), better known by her stage name Natalie Portman, is an actress with dual American and Israeli citizenship. Her first role was as an orphan taken in by a hitman in the 1994 French action film Léon, but mainstream success came when she was cast as Padmé Amidala in the Star Wars prequel trilogy (released in 1999, 2002 and 2005). In 1999, she enrolled at Harvard University to study psychology while still working as an actress. She completed her bachelor's degree in 2003.

In 2001, Portman opened in New York City's Public Theater production of Anton Chekhov's The Seagull. In 2005, Portman received a nomination for the Academy Award for Best Supporting Actress as well as winning the Golden Globe Award for Best Supporting Actress - Motion Picture for the drama Closer. She won a Constellation Award for Best Female Performance, and a Saturn Award for Best Actress for her starring role in V for Vendetta (2006). She played leading roles in the historical dramas Goya's Ghosts (2006) and The Other Boleyn Girl (2008). In May 2008, she served as the youngest member of the 61st Annual Cannes Film Festival jury. Portman's directorial debut, Eve, opened the 65th Venice International Film Festival's shorts competition in 2008. Portman directed a segment of the collective film New York, I Love You.

Jimmy Donal "Jimbo" Wales ( /ˈdoʊnəl ˈweɪlz/; born August 7, 1966) is an American Internet entrepreneur best known as a co-founder and promoter of the online non-profit encyclopedia Wikipedia and the Wikia company. Wales was born in Huntsville, Alabama, United States, where he attended Randolph School, a university-preparatory school, then earned bachelor’s and master’s degrees in finance. While in graduate school, he taught at two universities, but left before completing a PhD in order to take a job in finance and later worked as the research director of a Chicago futures and options firm. In 1996, he and two partners founded Bomis, a male-oriented web portal featuring entertainment and adult content. The company would provide the initial funding for the peer-reviewed free encyclopedia Nupedia (2000–2003) and its successor, Wikipedia.

On January 15, 2001, with Larry Sanger and others, Wales launched Wikipedia, a free, open content encyclopedia that enjoyed rapid growth and popularity, and as Wikipedia’s public profile grew, he became the project’s promoter and spokesman. He is historically cited as a co-founder of Wikipedia, though he has disputed the "co-" designation, declaring himself the sole founder. Wales serves on the Board of Trustees of the Wikimedia Foundation, the non-profit charitable organization he helped establish to operate Wikipedia, holding its board-appointed "community founder" seat. In 2004, he co-founded Wikia, a for-profit wiki-hosting service. His role in creating Wikipedia, which has become the world’s largest encyclopedia, prompted Time magazine to name him in its 2006 list of the world’s most influential people.
