While thousands of people attended the New York City parade to celebrate the U.S. Women's Team's 2016 World Cup win, a women's advocacy group decided to use the celebratory moment to combat sexism in FIFA.

The women's rights group known as UltraViolet held a demonstration to protest wage inequality at the first ticker tape parade for a World Cup champion women's soccer team in lower Manhattan on Friday.

According to the anti-sexism group, the winning women's team of the 2015 World Cup took home $2 million in prize money, while the men's team was awarded $35 million after winning the World Cup in 2014. Meanwhile, the USA men's team was awarded a whopping $8 million prize despite losing in the first round, reports Bustle.

To combat the gross pay discrimination in FIFA, Ultraviolet launched an anti-sexism ad campaign against FIFA, which kicked off at the New York City parade Friday morning. As part of the campaign, the women's rights group flew a banner from a plane around the city from 9 a.m. to noon that said, "UltraViolet: FIFA -- Equal Pay 4 Equal Play." The group also dispatched bike ads with equal pay billboards that can be seen throughout New York City all day.

"Our message to FIFA is simple: equal pay for equal play," said UltraViolet co-founder Nita Chaudhary in a press release, according to Time. "FIFA's antiquated pay discrimination isn't acceptable anymore."

UltraViolet, which has been demanding FIFA officials provide women athletes with equal pay since February, increased its pressure on FIFA following the USA team's World Cup win earlier this month. In addition, the organization launched a national petition calling for an end to pay discrimination against women, which has been signed by more than 70,000 UltraViolet members.
