Graphic Design – an Informative Speech

So I have to write an “informative speech” for, Speech class, and I obviously went the way of graphic design. Where it’s useful, who does it the most (career tracks), various ways to design (tablet, traditional + scans, photography, mouse/touchpad), etc…  Oh, hell, here’s the outline.

1. where it is used
   • adverts / billboards
   • logos
   • media covers
     • books
     • cds
     • dvd
   • web design 
2. media
   • flash
3. by whom
   • architects
   • animtors
   • web designers
4. how?
   • tablet
   • image integration / resources
     • traditional scans
     • photography stocks / scans
     • digital stocks / scans
   • mouse/touchpad

Feel free to add anything (relevant and) useful to the list.  :]
