Peter Wayner has picked up on the trend of the world seemingly now needing a constant stream of new type in his piece "Down with Helvetica: Design Your Own Font." It's about the desire to move away from the fonts everyone has access to and hiring out to create a unique design for each project. In the piece, they get into conversations with a number of different designers like Charles Andermack and about companies like FontStruct, as well as talking to these client people who are now thinking along these lines and are providing the bread and butter for the aforementioned designers and companies. Here's a bit how Andermack (or Chank Diesel as you may know him) offers an inexpensive custom handwriting font service to people and then turns it around to sell as something new:

Mr. Andermack asks clients to copy a collection of words in their handwriting, then scans the letters into his computer and produces a font. The only catch is that Mr. Andermack keeps the rights to resell the font to others. He publishes a collection of distinctive handwriting fonts to ad directors who want to capture a particular style or era. Your handwriting could end up in the next bundle. Exclusive rights cost more.
