[6] Mars left a PhD program in genetics to undertake an unpaid internship at public radio station KALW in San Francisco.
[7] In partnership with the Knight Foundation and the Public Radio Exchange (PRX), Mars also created the podcast collective Radiotopia.
The show later left Radiotopia and is now distributed independently as What Roman Mars Can Learn About Con Law.
[16] 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.
[17] 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.
