use of the scratch logo and initials "WWF", with only the cover art and menu screens of the Tagged Classics displaying the initials "WWE". They served as a more faithful representation of archived WWF material than the more recent Royal Rumble, WrestleMania, SummerSlam and Survivor Series anthologies that were released using the WWE logo before 2012. They also do not feature the WWE watermark and digital on-screen graphics like more recent WWE Home Video releases do. They do however contain the watermark and digital on-screen graphics for the specific time frame. For instance, there is no watermark used up to 1994, past that; the Golden Era logo is used, then the New Generation Era logo from 1995 onward, and finally the scratch logo for all the Attitude Era discs. Some theme music is dubbed over on WWE Home Video releases, but not on these Tagged Classics sets. For instance, on the WrestleMania: The Complete Anthology box set — Demolition's entrance theme is dubbed over with generic production music. This is done to save money on paying royalties to certain artists and music production companies. These sets have all the original music included unless they were dubbed over in the original VHS/DVD releases, for example, Unforgiven 1999's main event video package featured music by Fear Factory and System of a Down, but it was dubbed over on the VHS release and thus is also dubbed over on the corresponding Tagged Classics release. It is not known exactly why these sets are exempt from blurring and editing, but many theories have arisen. The first is that they are direct re-releases from the past. The second is that they are only available in the United Kingdom and Europe, and therefore are exempt from legal restraints because of this. The third reason is that Silver Vision is a third party licensee of WWE Home Video in the United Kingdom, and technically this is not WWE releasing these sets. Also, the court order required the company to remove both auditory and visual references of "WWF" in its library of video footage outside the United Kingdom. Silver Vision are legally allowed to release these events with the various iterations of the WWF logo intact, and references of "WWF" are also allowed to remain. In July 2012, WWE came to a new agreement with the World Wildlife Fund that allows for WWE to abstain from editing WWF
