So previously it was illegal for people to make parody  videos / mash ups / spoofs using footage or music they didnt own because it breached copyright laws.  They would be made and uploaded to You Tube and then often the company that owned the footage or music would report the video and get it removed for breaching the copyright laws.. the government have announced that all that is changing and that these will now become legal.

1) give 3 reasons why companies might not like this law to be changed

2) Try and explain how it might benefit them in the long run

3) Why do you think audiences enjoy watching these types of videos?  Try and give 3 reasons with examples.
