What is the "blue sky" period?

The "blue sky" period refers to a time during the creative process, particularly in writing, where all ideas are considered valid and allowed to be explored without restrictions. During this phase, typically lasting from two to four weeks, creative teams, like those on television shows, brainstorm freely without worrying about feasibility or conflicts. This unrestricted exploration encourages the generation of many ideas, fostering a creative environment where innovative and unique concepts can emerge. The term was notably used in the context of planning a television season, where writers would entertain all possibilities, such as plot ideas that might seem outlandish or unworkable under normal circumstances 1.
