Demographic
The demographic for D83 would be a ABC demographic who are well educated because they will have to have an interest in the cold war and at the same time they would need the attention span in order to read all of the subtitles and sat up to date on them.

Psychographic      
the two that i would chose are as followed, the first being resigned because i think their strict personality would be able to deal with the subtitles and those who are not would probably get bored and want to stop reading the subtitles  
the second being reformer because it is not a well known show so they would have so have seen it for themselves and still want to watch it. this means that they don't care what others think and they want to watch the show because they enjoy it  

how does this affect the text?
this will affect it because it means they are able to use more sophisticated words in order to get the details about the cold war out. they will most likely use slang words and jargon from the time in order to  make it feel as authentic as possible.                                                                                                                

How does this effect advertising
They will be wanting to use the sorts of colours that are going to be in the show so that you see the colour scheme and recognise the show easier. This will mean they will base their whole marketing and advertising on the show and making it relate to the show. They will also have photos of the characters in order to make sure you know who they are. For this program this might not help because the show isn’t well known so people won’t give it a second glance because people want to see a star they know this could lead to them putting other things in their posters and advertising.
