Early life Mars left a PhD program in genetics to undertake an unpaid internship at public radio station KALW in San Francisco.
In 2004, he produced a program called Invisible Ink on KALW.
99% Invisible
Mars and his radio show, 99% Invisible, have been credited in the mainstream press as an innovative form of radio production, defining a new movement of independent radio and podcast creators. In 2016, Mars and Justin McElroy used asynchronous podcasting, a method where each person recorded their portions separately and later combined them to create a podcast episode. This new technique was used to create the first episode of Smart Stuff, which started with My Brother, My Brother and Me episode 316 and was completed in 99% Invisible episode 225.
99% Invisible Inc., the company that produces 99% Invisible, was sold to SiriusXM's Stitcher Radio in April 2021. Mars donated $1 million from the sale to Radiotopia. The book debuted on the New York Times Best Seller list for hardcover non-fiction.
Radiotopia
In partnership with the Knight Foundation and the Public Radio Exchange (PRX), Mars also created the podcast collective Radiotopia. The Public Radio Exchange has hired Mars to curate a radio program called Remix, which is syndicated by at least 14 public radio stations across the US. In June 2017, Roman Mars began cohosting the constitutional law podcast What Trump Can Teach Us About Con Law with Elizabeth Joh, a professor of the subject at University of California, Davis, School of Law.
Use of crowdfunding Mars notably used the Kickstarter crowdfunding platform to support 99% Invisible, raising over $170,000, making it the highest-funded journalism project ever, and the second highest-funded project across the platform's entire publishing category. In November 2013, 99% Invisibles season four Kickstarter campaign received 11,693 backers raising over $375,000. The original goal of $150,000 was raised in 92 hours. Following this success, Mars introduced another campaign to build season two of Radiotopia, a collection of seven storytelling podcasts: 99% Invisible, Fugitive Waves, Love and Radio, Radio Diaries, Strangers, Theory of Everything, and The Truth. Its original goal of $250,000 was funded within six days. By the time the campaign closed on November 15, 2014, it had more than doubled its original target, achieving $620,412 from 21,808 backers, making it the most-funded Kickstarter project in the publishing and radio and podcast categories. Meeting its 'stretch goals' allowed Radiotopia to add three podcasts hosted by women (Criminal, The Heart, and The Allusionist), host a series of events, provide more content, wage increases and paid internships, and create a pilot development fund to find new, talented producers and hosts not covered by traditional radio. Ultimately, the fundraising allowed for a fourth podcast, Mortified, to be added to the collective.
