So, a long time ago, there was a company called Anglia Television that made TV shows and movies. Another person named Mr. Reed wanted to record one of their movies and sell copies of it to make some money. This is not allowed because it is like stealing someone else's work.
Anglia Television found out about this and they took Mr. Reed to court. The court said that Mr. Reed was wrong because he couldn't make copies of their movie without their permission. This is like how you can't just take someone else's toy without asking first.
So, the court made Mr. Reed stop making copies of Anglia Television's movie and he had to pay them money for breaking the rules. This is like if someone takes your toy without asking, they have to give it back and say sorry or give you a new toy.
This court case helped make sure that people have to ask permission before using someone else's work and it also helped protect the rights of the company who made the movie.
