Twenty-two companies have pulled their ads from Bill O'Reilly's show after a report revealed women had accused the Fox News host of sexual harassment, verbal abuse, and inappropriate behavior.

O'Reilly's show may be taking a financial hit after BMW, Mercedes, Hyundai, Ainsworth, Constant Contact, Sanofi, GlaxoSmithKline, Allstate, Esurance, Untuckit, Mitsubishi, T. Rowe Price, Credit Karma, Coldwell Banker, Lexus, Bayer, Wayfair, Orkin, True Car, MileIQ, The Wonderful Company, and the Society for Human Resources Management all announced they would be removing their ads.

The list is expected to grow, with the Sleeping Giants setting their sights on The O'Reilly's Factor after the anonymous group first launched a campaign that led Breitbart to lose more than 1,750 advertisers.

The backlash comes after a report in The New York Times revealed O'Reilly and Fox News paid five women $13 million to settle four cases of sexual harassment and one incident of verbal abuse in the past 15 years.

In addition to the five women, Wendy Walsh, a regular on his show, along with Andrea Tantaros, a former Fox News host, also accused the 67-year-old of inappropriate behavior.

The National Organization for Women is now calling for Fox News to fire O'Reilly, saying the network is 'too big and too influential to simply let this go'.

While Hyundai does not currently run ads on The O'Reilly Factor, it pulled spots on future episodes. BMW said it suspended advertising on the show due to the recent allegations

Credit Karma, Lexus, Mercedes, Hyundai, Bayer, and Wayfair, all announced they were joining the growing list of companies pulling their ads

Mercedes Benz was one of the first companies to announce the decision on Monday afternoon, and more than a dozen others followed suit by Tuesday night.

While Hyundai does not currently run ads on The O'Reilly Factor, it pulled spots on future episodes, saying it wanted to partner with companies and programming that share its values of inclusion and diversity.

BMW said it suspended advertising on the show due to the recent allegations, as did financial firm T. Rowe Price, Sanofi, Ainsworth Pet Nutrition and Constant Contact.

While the move certainly presents a public relations headache, it remains unclear whether the decision to pull advertising from O'Reilly's show will directly impact Fox News' bottom line.

Paul Rittenberg, the executive vice president of advertising sales at Fox News, issued a statement saying: 'We value our partners and are working with them to address their current concerns about the O'Reilly Factor.

'At this time, the ad buys of those clients have been re-expressed into other FNC programs.'

That may very well change, since the Sleeping Giants have started compiling a running list of advertisers so activists can pressure the companies to reconsider their support.

The anonymous group, familiar with the ins and outs of digital marketing, first launched a campaign against Breitbart - leading 1,759 companies to blacklist the website.

The group wrote: 'Despite the fact that we’ve been focused on the hate and bigotry of Breitbart News, we felt it necessary to take action against Mr. O’Reilly because of his clear disregard for women and minorities.

NOW President Terry O'Neil called for an independent investigation into Fox's workplace culture on Tuesday and said: 'The reported use of [O'Reilly's] powerful position to repeatedly manipulate women reveals a cruel misogyny that runs to the core of his character.

'For too long women have endured dangerous sexism at the hands of powerful men and powerful institutions.

'Fox News is too big and too influential to simply let this go. Women have the right to go to work without facing harassment. Fox News apparently doesn’t get that basic concept,' she added.

While NOW is calling for O'Reilly to be fired, that may prove to be difficult considering the TV host is Fox News' top revenue producer.

O'Reilly brought in more than $178 million in ad dollars in 2015 and $118.6 million in the first nine months of 2016, according to research firm Kantar Media.

O'Reilly, in his first televised appearance since the Times' story on sexual harassment allegations against him, made no mention of the claims on Monday

O'Reilly and Fox reportedly paid five women a total of $13million in exchange for confidentiality and an agreement that they would not pursue litigation, according to the Times.

The first settlement was reached in 2002 after O'Reilly screamed at producer Rachel Bernstein, according to witnesses and other employees.

Bernstein soon left the company with an undisclosed sum, although those familiar with the deal said it was significantly smaller than the four settlements that followed over the course of the next 15 years.

Andrea Mackris, who worked as a producer on his show, said O'Reilly called her while he was masturbating, told her to buy a vibrator, and described his sexual fantasies with her, according to a 2004 lawsuit.

She settled with O'Reilly to the tune of $9million and a public statement that asserted there was 'no wrongdoing whatsoever', the Times reported.

When 21st Century Fox was investigating sexual harassment allegations surrounding former CEO and Chairman Roger Ailes in 2016 they learned of another settlement O'Reilly made in 2011.

Rebecca Gomez Diamond, a host on the Fox Business Network, revealed her recorded conversations with O'Reilly after the network told her they would not be renewing her contract, those familiar with the case told the Times.

She settled with O'Reilly for an undisclosed sum.

The network also struck deals with Laurie Dhue and Juliet Huddy in 2016 for more than $1million each.

While the five women are now bound to confidentiality, another two who did not settle have made claims against O'Reilly's inappropriate behavior.

Tantaros turned down a settlement of nearly $1million, and launched a lawsuit against both Fox and Ailes, who was ousted in July with a reported $60million golden parachute.

While O'Reilly is not a defendant in the case, Tantaros said he invited her to a 'very private' stay with him on Long Island, and made comments about seeing her as 'a wild girl', according to the lawsuit.

Her psychologist also testified saying Tantaros complained about O'Reilly's unwanted advances, but Fox investigated and called her an 'opportunist'.

Walsh, who was a frequent guest on O'Reilly's show, said he promised to make her a network contributor when the two went out to dinner.

But Walsh turned down an invitation to visit O'Reilly's hotel suite after dinner and her rejection apparently angered him, according to Walsh.

She was never made a contributor, and a producer said she wasn't invited back on the show after four months due to declining ratings.

Walsh never filed a complaint for fear of harming her career.

O'Reilly issued a statement in response to the allegations, saying: 'Just like other prominent and controversial people, I'm vulnerable to lawsuits from individuals who want me to pay them to avoid negative publicity.'

21st Century Fox also backed him in their own statement, which said: 'Notwithstanding the fact that no current or former Fox News employee ever took advantage of the 21st Century Fox hotline to raise a concern about Bill O'Reilly, even anonymously, we have looked into these matters over the last few months and discussed them with Mr. O'Reilly.

'While he denies the merits of these claims, Mr. O'Reilly has resolved those he regarded as his personal responsibility.

'Mr. O'Reilly is fully committed to supporting our efforts to improve the environment for all our employees at Fox News.'

After the bombshell report was published this weekend, Walsh's attorney Lisa Bloom said: 'The network has become the Bill Cosby of corporate America.

'How many women must come forward before Fox News complies with the law and respects women?'

In addition to the allegations lodged against O'Reilly, parent company 21st Century Fox is still dealing with the legal fallout from sexual harassment charges against former Ailes.

On Monday, Fox News contributor Julie Roginsky filed a sexual harassment lawsuit against Ailes, saying she was denied opportunities after she rebuffed Ailes' advances and that current management sought to keep her complaints quiet.
