Professional Practice: Dissertation Topic Ideas

Tonight I have been researching some dissertation topic ideas ready for my tutorial with Chris Hunt tomorrow. The main topic that has appealed to me the most has been how Netflix/Lovefilm platforms has changed the viewing habits of a television audience. There could be difficulty with this topic though as it is quite recent and there won't be much in books or research to work with. I think i would enjoy writing about this subject though because it is quite familiar to me.
