"Left of Dial's Essential Listening Poll gathered 300 audio creators, podcast hosts, writers, and scholars from around the world for the first time to create the definitive list of the most groundbreaking, influential, and beloved podcasts of all time. Voters were asked to share the five shows that are most important and meaningful to them." - https://www.leftofdialmedia.com/essential-listening-poll
The reason why there are 107 podcasts is because Left of the Dial ranked eight separate podcasts at #100.
#33 was listed as "Missing & Murdered: Finding Cleo" which is the current title of the RSS Feed, but the first season was subtitled "Who Killed Alberta Williams?" and that's where List Challenge's cover art comes from. I decided the list was about most influential *podcasts*, not seasons, and thus it was unnecessary to make a separate listing for the second season.
I am not employed by Left of the Dial and this List Challenge is "unofficial" if that wasn't obvious.
