Bailey Sarian

The channel series, Dark History, takes an active approach at highlighting the histories of people and communities that have been oppressed and marginalized across US and world history, more specifically, Black, Indigenous, and people of color (BIPOC), the LGBTQ+ community and people of different socioeconomic status. There are videos that dive into the history of death and minimum wage, the history of the AIDs epidemic, the dark history and treatment that lead to the Americans with Disabilities Act, mass sterilization of Puerto Rican women, Japanese internment camps in the US, the history of Henrietta Lacks, the Radium Girls, and gay conversion therapies.

Stories often include violent subject matter intended for more mature audiences such as physical, psychological, emotional and sexual abuse, child molestation, mutilation, cannibalism, eugenics, and incest to name a few. In-video disclaimers are provided for extremely disturbing or graphic content. Thumbnails tend to use sensationalized and gruesome images depicting weapons, blood splatter, and words such as "murder", "suicide", and "killer". Sarian has stated her intentions are never to disrespect the victims of the true crime stories she investigates and shares.

Stories and histories include mature sexual themes and events not suitable for young children. Episodes may detail sexual encounters. Some episodes investigate the origin of sex toys and pornography. Bailey frequently makes lewd remarks and sexual innuendos. Many of the videos with these themes are clearly labeled as such.

Frequent use of explicit language ("a–hole", "c–t", "p—y", "f–k", "whore", "bitch", and much more).

Stories include events of drug and alcohol use and abuse, as well as victims being subdued through the forced use of drugs and/or alcohol. Bailey tells histories of the use and creation of particular drugs and alcohol. Bailey sometimes talks about events in which she drinks alcohol (at a legal age).
