The big bang theory is a situation comedy. The show conforms to the codes and conventions of situation comedy as its: set in a place where the characters all meet up to be together for example in this show it is set in the apartment of the main characters, it has a set of characters that are stuck together in a situation from where they cannot escape in this case its the apartment, There is normally a resolution by the end of the show and Events happen during an episode to disrupt the status quo. The show runs in a linear format as everything happens in order. The show is also multi-strand as it often has one main story with another storyline. The narrative of the show is closed and restricted as we find out things along with the character and the show ends with a resolution. What makes this show different to other sitcoms is that although it has new story lines it still contains traits from the previous stories this is because they want old audiences to feel comfortable with the show as well as allowing new audience to watch the show without getting confused, thus allowing for more viewers increasing the ratings of the show. The show targets teenagers. Proof of this would be the fact it airs on e4 a channel made to target the teen range. Along with people with an interest in science to accomplish this it uses witty humour and storyline that people may be able to relate to. Other ways it targets the audience is by having a myspace this way they can advertise the show virally and which the target audience may feel comfortable with this is similar to the way skins advertised its show. Although the show is based around science and is fiction it is not science fiction because it doesn't contain the elements of science fiction I think this is what makes the show more relatable to the audience because its not over the top with its stories.
