The show became one of BuzzFeed's most watched shows, which led the series to start streaming on Hulu and Amazon Prime in 2018. Most episodes would be followed by a question and answer episode, entitled BuzzFeed Unsolved Postmortem, where Bergara and Madej answer questions sent in by viewers about the week's episode. The show was filmed primarily in the United States, with some episodes filmed in separate locations in the UK and Mexico. While the topics of discussion are often morbid, most episodes are presented in a comedic manner, cutting between Bergara's voiceover of the episode's topic and comedic discussion with Madej.

The show is split into two alternating themes, with each season seeing Bergara and co-host Shane Madej discussing either unsolved crimes in BuzzFeed Unsolved True Crime or investigating alleged haunted locations and demonic possessions in BuzzFeed Unsolved Supernatural. It first appeared on the YouTube channel BuzzFeed Blue and was later given its own flagship channel BuzzFeed Unsolved Network. BuzzFeed Unsolved (also known as simply Unsolved) is a documentary entertainment web series created by Ryan Bergara for BuzzFeed that ran from Februto November 19, 2021.
