Brother, wait until you learn about the associate press.

In U.S. copyright law, the four factors evaluated to judge fair use are:

1: Purpose and character of the use: including whether the use is commercial or nonprofit educational, and whether it is transformative.

2: Nature of the copyrighted work: for example, whether the work is more factual or more creative.

3: Amount and substantiality used: both how much was taken and whether it was a qualitatively important part of the work.

4: Effect on the market: whether the use harms the potential market for or value of the original work.

Courts weigh all four factors together. There is no fixed rule like "under 30 seconds" or "under 10%." GN's use seems to satisfy all four factors.
