What is the MPLC? Is it related to PPL and PRS for Music or PPL PRS Ltd?

In June 2016, there was a change to copyright law. Prior to this, if there was no entry fee, premises could legally play films (including TV programmes) without having to obtain a licence from the owners of rights in those films. The change in law removed the exemption and means that these owners can now license businesses for playing the TV in their premises, even where no admission fee is charged. The MPLC is the Motion Picture Licensing Company, an organisation which controls rights in certain films and TV programmes and therefore offers a licence for this use.

The MPLC is not in any way related to PPL and/or PRS for Music and/or PPL PRS Ltd. It is a separate company that represents a different set of rightsholders.
