Lost

I believe that the intended demographic for the Television series Lost is a wide mainstream audience, because of the use of an ensemble cast which helps to appeal to a larger more varied group. This is because different people can relate to certain characters in the series. Also the show conforms to certain stereo types which viewers are familiar with meaning that they can decode characters easier causing them to be gratified. 

Another convention which lost adheres to in order to appeal to a mainstream audience is the employment of propps character theory. An example of this is with the character Jack who is directly called the 'Hero'. This conventional character type is familiar to cine literate audiences and is a common narrative technique. 

Lost appeals mainly to a passive audience with many common techniques to help gratify a large mainstream audience, such as enigma codes. These help to keep the audience interested in the text. Often the enigma codes are directly before advert breaks in order to ensure that the audience remain.
