Laws and such

The question of laws requiring a label placed on published horoscopes is best answered by reference to the actual history:

1735 brought in the Witchcraft Act of 1735, banning all claims to be able to summon spirits, tell fortunes, etc. It is widely thought to in fact only apply to *false* claims (i.e. fraud) - thus allowing for the existence of true claims - it is based on a contemporary belief that all such claims are false, as the claimed abilities are impossible.

In 1951 this was repealed by the Fraudulent Mediums Act 1951, and this law, containing an escape clause for the "medium", is in essence the origin of the "for entertainment" wording.

In 2008, this act, too, was repealed and replaced by a batch of new Consumer Protection Regulations, and this is probably the reason for the wording disappearing (that and a certain amount of apathy/unawareness on the part of the public and of plod).
