Huffington (née Stassinopoulos) was born in Greece on July 15, 1950. She grew up in Greece and moved to England at the age of 16 to attend the Girton College at Cambridge University. She graduated with a degree in economics. At Cambridge, she was the President of the Cambridge Union Society, the university’s prominent debate club. Because of this position, she became a frequent guest of the BBC Radio 4 show Any Questions? After acting as a discussion panelist for several BBC television shows, she became the first female host of the late night talk show Saturday Night at The Mill.
She moved to the United States in 1980, and married Michael Huffington in 1985. She published several articles for National Review in the early 1980s, but her real rise to public prominence came when she began supporting her husband’s campaign for a seat in the U.S. Senate. Two years later, Huffington reported on the 1996 presidential elections for Comedy Central. She campaigned herself in an unsuccessful bid for the governorship of California in the 2003 recall election.
In 2005 Arianna Huffington founded the news website The Huffington Post with Kenneth Lerer and Jonah Peretti.
