The video 'Origin of Everything: Why Do We Go to Prom?' from the series 'Origin of Everything' explores the cultural significance of prom in American society. Prom, short for 'promenade,' started as a formal school dance in the late 19th century, evolving into a rite of passage reflecting the transition from adolescence to adulthood. It delves into the socio-economic aspects, noting prom's affordability issues, the average cost being $919 per student as per a 2015 Visa survey. Utilizing insights from ethnographer Arnold Van Gennep on 'rites of passage,' and critiques from filmmakers, the video examines class dynamics and prom's portrayal in cinema, like John Hughes' 'Pretty in Pink.' Prom remains a cultural staple symbolizing social mobility, albeit with ongoing debates about its role in contemporary teen life and representations in media. The discussion spans cultural shifts, societal critiques, and the enduring allure of this high school tradition.
