What an interesting question. I've always been intrigued by the
enormous scope of human creativity, but I've never stopped to consider
the list of things that someone might create that another might find
worth licensing or otherwise paying for.
Although your question didn't explicitly say so, you seem to be
looking for a list of creations that folks can write down.
Businesses strike big-time licensing deals with the likes of Tiger
Woods, or Paris Hilton, but I don't think you quite had in mind the
types of things that Mr. Woods or Ms. Hilton create as belonging on
your list. However, please feel free to correct me if I'm mistaken.
The list, below, is largely of my own making (**...I'm making a list,
checking it twice...**) and from my own experience as someone who has
created things himself, as well as enjoyed the results of the
creations of others.
I trust it fully answers your question.
However, please don't rate this answer if you find you'd like
additional information. Just post a Request for Clarification, and
I'll be happy to assist you further.
Blurbs -- for books, records, CDs, or other promotional copy
Cards--greeting cards, birthdays, anniversary
Cheers (for sporting events, etc).
Concepts -- very brief description of a script/show idea
Google Answers (couldn't resist!)
Interactive scripts (e.g. computer game dialogs)
Languages (e.g. create a Klingon or Orc vocabulary)
Legal materials -- wills, contracts, etc
Loglines -- brief description of a script/show idea
Phrases, e.g. Trademarks, slogans, bumper-stickers, etc.
Premise -- mid-length description of a script idea
Specialty scores -- such as Labanotation for dance choreography
Synopsis -- Script summary, moderately detailed
Treatment -- script summary, longer than a synopsis
Word and Number Puzzles (crosswords, sudoku, anagrams, word jumbles, etc)
Of course, each entry on the above list represents fairly broad
categories that can be further sub-divided into an almost unlimited
number of types of creations -- how many different sorts of research
reports are there, one wonders?
However, I think the list provided is a pretty good first take on the
types of things you (presumably) had in mind.
Of course, if I've missed the mark at all -- or even omitted some
items that would be of interest to you -- just let me know, and I'll
be happy to continue working on this for you.
All the best, for the holiday season and the new year.
