[6][1] She was a popular conservative commentator in the mid-1990s, after which, in the late 1990s, she offered liberal points of view in public, while remaining involved in business endeavors.

[12] She stepped down from her role at The Huffington Post in August 2016 to focus on a new startup, Thrive Global, a behavior change technology company with the mission of improving productivity and health outcomes.

[13] Huffington was born Ariadnē-Anna Stasinopoúlou (Αριάδνη-Άννα Στασινοπούλου) in Athens, Greece,[4] in 1950,[14] the daughter of Konstantinos (a journalist and management consultant) and Elli (née Georgiadi) Stasinopoulou, and is the sister of Agapi (an author, speaker, and performer).

A relationship developed, of which she wrote, after his death: "He wasn't just the big love of my life, he was a mentor as a writer and a role model as a thinker.

From March to April 1980, Huffington joined Bob Langley as the co-host of BBC1's late-night talk and entertainment show Saturday Night at the Mill, appearing in just five editions before being dropped from the program.

She became known as a reliable supporter of conservative causes such as Newt Gingrich's "Republican Revolution" and Bob Dole's 1996 candidacy for president.

She teamed up with liberal comedian Al Franken as the conservative half of "Strange Bedfellows"[25] during Comedy Central's coverage of the 1996 U.S. presidential election.

During that year, she did a weekly radio show in Los Angeles called Left, Right & Center, that "match[ed] her, the so-called 'right-winger', against self-described centrist policy wonk Matt Miller, and veteran 'leftist' journalist Robert Scheer.

"[16][27] In an April 1998 profile in The New Yorker, Margaret Talbot wrote, "Most recently, she has cast herself as a kind of Republican Spice Girl – an endearingly ditzy right wing gal-about-town who is a guilty pleasure for people who know better."

[30] Huffington headed The Detroit Project, a public interest group lobbying automakers to start producing cars running on alternative fuels.

The project's 2003 TV ads, which equated driving sport utility vehicles to funding terrorism, proved to be particularly controversial, with some stations refusing to run them.

[31] In a 2004 appearance on The Daily Show with Jon Stewart, she announced her endorsement of John Kerry by saying, "When your house is burning down, you don't worry about the remodeling.

She was also a regular panelist on the nationally syndicated weekend radio program, Both Sides Now with Huffington & Matalin,[33] hosted by Mark Green.

Huffington serves on the board of directors of the Berggruen Institute,[34] the Center for Public Integrity,[35] Uber,[36] and Onex Corporation.

[47] In 2012, The Huffington Post became the first commercially run United States digital media enterprise to win a Pulitzer Prize.

[60] Huffington at one point was the co-host of the weekly, nationally syndicated public radio program Both Sides Now, along with Mary Matalin, former top aide to the George W. Bush administration.

About Clinton resigning, she wrote, "Only some act of sacrifice can begin to restore the image of the President that we are left with from the Starr report – a man of staggering narcissism and self-indulgence, whom nobody dared gainsay, investing his energies first in gratifying his sexual greeds and then in using his staff, his friends, and the Secret Service to cover up the truth.

"[61] In November 2008, Huffington joined the cast of Seth MacFarlane's animated series The Cleveland Show, where she lent her voice to the wife of Tim the Bear, also named Arianna.

She headlined a debate against radio co-host Mary Matalin on current world events, political issues, and the local Buffalo economy.

The University at Buffalo "Distinguished Speaker Series" has featured a multitude of world-renowned politicians and celebrities such as Tony Blair, Bill Nye, Jon Stewart, and the Dalai Lama.

[77] The couple later moved to Santa Barbara, California, and, in 1992, Michael ran as a Republican for a seat in the U.S. House of Representatives, winning the election by a significant margin.
