The DPP list of 'video nasties' was first made public in June 1983. The list was modified monthly as prosecutions failed or were dropped. In total, 72 separate films appeared on the list at one time or another. Thirty-nine films were successfully prosecuted under the Obscene Publications Act but some of these films have been subsequently cut and then approved for release by the BBFC. The remaining 35 were either not prosecuted or had unsuccessful prosecutions.
