South Park has come a long way since its inception.

When South Park creators Matt Stone and Trey Parker agreed to star in the 1998 comedy BASEketball, they did so under the assumption that their crude cartoon would be canceled by the time filming of the movie commenced. But here we are, 20 years later, and their hit show is still finding new ways to poke fun at the world around us in hilariously offensive fashion.

These days, South Park might not make headlines for causing outrage like it used to, but the show’s ability to continuously tap into the zeitgeist and ridicule whatever is topical at the time has kept it relevant.

Youtube user KaptainKristian’s video essay chronicles the show’s evolution; from its origins as a humble holiday short film to the enduring pop culture phenomenon it is today. He also explores how it’s been able to bypass censors while simultaneously pushing the boundaries of what’s acceptable television content. Stone and Parker’s humor is for an acquired taste, but there’s no denying that their show has impacted the medium.
