Final answer:
Creative Commons is the form of copyright where creators share their works with certain allowed usage rights, balancing protection and collaborative exchange.
Step-by-step explanation:
The form of copyright where content creators are able to share their work and allow others to use it based on varied boundaries is known as Creative Commons. Creative Commons is a licensing system that enables creators to grant certain usage rights to the public while still maintaining copyright over their work. Options typically include allowances for certain types of uses, such as noncommercial purposes. The Creative Commons license also outlines how the work may be adapted or changed, and requires that the original author is credited for their work. This approach to copyright provides a balance between protecting the author's rights and allowing for a more flexible and collaborative exchange of creative work.
