Here is a nice, concise description that might yield some quotes for you:
The study of the media revolves around the following key concepts.
Audience
Genre
Ideology
Institution
Narrative
Representation
When approaching the analysis of any text, you need to consider the
above - these are the things which drive a text's construction and reception. Your ME1 exam in particular will ask you to analyse a text whilst focusing on one of these concepts.
You will also need to consider codes and conventions - technical, symbolic and verbal - and different potential (preferred and oppositional) readings of a text.
Success in Media Studies is heavily reliant on you knowing the right word to use to describe all this. Terminology is there to help you, to make your descriptions accurate - use it.
There is also an excellent Effects Glossary at cultsock which offers clear explanations of many of the media terms you will encounter.

Here is another from Rutgers:
The Center's Mission
