Ideas that once seemed unpopular, even radical, yet changed history are the jumping off point for a new iHeartPodcast Network show aimed at inspiring listeners to speak up and spark change. The podcast is called Unpopular and the Yves Jeffcoat-hosted show discusses the rebels and revolutionaries who created lasting social change. During each episode, Jeffcoat explores the protesters that inspired progress and the groundbreaking ideas that shattered traditional power structures. Her subjects range from Italian astronomer, physicist and engineer Galileo to Nigerian teacher, political campaigner and women's rights activist Funmilayo Ransome-Kuti. It will not only tell their stories but also discuss the opposition each crusader faced for speaking out.

In a trailer for the show, Jeffcoat says they’ll connect the dots between their history and current events. “We can be so quick to dismiss people’s ideas when they seem too big,” she says. “It’s easy to reject change. It’s harder to be open to new ideas.”

The first episode tells the story of the Hunkpapa Lakota leader Sitting Bull, who dedicated his life to making sure his people and culture could persist.

“Without protest there would be no progress. I for one am thankful there were plenty of people in history who refused to accept the conventions of their time,” Jeffcoat says. “It’s human nature to value stability and patterns. It makes sense for us to be resistant to change and being wrong just sucks. But change is inevitable and we have to think forward if we’re going to move forward—even if it costs us.”

Unpopular will publish new episodes each Tuesday.
