  The impact of real world events on fictional media is particularly apparent
in the American cartoon series The Simpsons. While there are often very direct
pop culture references evident in the dialogue and visual gags of the show,
subtle changes in tone or sentiment may not be so obvious. Our aim was to use
Natural Language Processing to attempt to search for changes in word frequency,
topic, and sentiment before and after the September 11 terrorist attacks in New
York. No clear trend change was seen, there was a slight decrease in the
average sentiment over time around the relevant period between 2000 and 2002,
but the scripts still maintained an overall positive value, indicating that the
comedic nature of The Simpsons did not wane particularly significantly. The
exploration of other social issues and even specific character statistics is
needed to bolster the findings here.
