How do cartoons like Robot Chicken not get sued for copyright infringement when they use iconic images like Charlie Brown?

Answer 1

The fair use section of the copyright law protects use in parody; many view this as an extension of free speech.

Answer 2

Cartoons like Robot Chicken often fall under the category of parody, which is considered fair use under copyright law. Parody allows creators to use copyrighted material in a transformative way for commentary or comedic effect without obtaining permission. As long as the use of the copyrighted material is transformative and does not harm the market for the original work, it is likely protected under fair use.
