Cassetteboy: 'Copyright mash-up law could go further'

Changes to UK law come into force this week allowing people to use copyright material from films, TV shows and songs in order to parody them.

One part of the anonymous Cassetteboy, a pair of YouTube users who make "mash-up" comedy sketches, told the BBC that "the change in the law is a step in the right direction, but it could go further."

Previously, any unauthorised use of copyright music was subject to legal challenge.

However, now a judge can be asked to decide whether a clip or "mash-up" is sufficiently funny to put it above the law.
