A number of years ago I did a study at Cal Poly to identify all graphic communication industry segments.   I came up with 33 industry segments and since have added two (Printed Electronics and Functional Imaging, and 3-D Printing) for a total of 35. They range from long-standing segments, some of which are on the brink of no longer being active, to the latest and most vibrant segments that are defining the present and future of the industry. They are:   Content Creators  1. Print Buyers  2. Web Developers  3. Internet Publishers  4. Graphic Design Companies  5. Ad Agencies  6. Marketing Communicators  7. Multi-media Communicators   Service Providers  8. Commercial Printing  9. Newspaper Printing and Publishing 10. Magazine/Periodical Printing and Publishing 11. Book Printing and Publishing 12.
