The Video Retailers Association were alarmed by the apparently random seizures and asked the DPP to provide a guideline for the industry so that stockists could be made aware of the titles which were liable to be confiscated. The DPP recognised that the current system, where the interpretation of obscenity was down to individual Chief Constables, was inconsistent and decided to publish a list that contained names of films that had already resulted in a successful prosecution or where the DPP had already filed charges against the video's distributors. This list became known as the DPP list of "video nasties".
