So much of the world revolves around groups. Who you have common interests with, who lives relatively close to you. If you look deeper into these groups, it can be broken down even further. The people that live close to you usually come from similar financial situations. Social groups can be created from religious views, race, gender, and even further.
Glee is a sitcom that addresses these social groups head on, portraying kids that are stepping outside of their usual circles, coming from many different backgrounds. Rich kids. Poor kids. Jewish kids. Athletic kids. Smart kids. Gay kids. Straight kids.
The diverse population of the Glee club contributes greatly to the club’s success. Everybody brings another talent to the table, whether it be choreographing, being able to hit a high note, or simply being able to attract more members from friends they may have from other interests.
The ability to portray all of these different types of people through one television show, while also including different songs, with an element of humor is important to television. Glee makes it clear that people, no matter how different they may be, are welcome and can find friends in the most unlikely places.
In addition, these people do not only make friends, but they find success, but not without also finding failures. The glee club lost at Nationals only to come back the next year to win Nationals. The football team only won one game, but then going on to win the state championship in the future. Main character, Rachel Berry, got into her dream school NYADA after blowing her first audition.
Glee was a successful sitcom because of the way that it broke the stereotypes of portraying white upper class families like many other sitcoms that succeed in everything that they attempt. Glee is a group of misfits, with disabilities and things that would be assumed to set them back, that succeed, but only not without experiencing failures on the way.
