The document discusses stereotypes in television casting and characters. It notes that the stereotypical popular girl role often has blonde hair in shows like Glee, High School Musical, The Big Bang Theory, and Ned's Declassified. It also points out that many shows include an ethnic minority character as a main character, though this is less common in The Inbetweeners. The document suggests including a character of an ethnic minority in their own program to address political correctness.
