The Act is relatively short, divided into 5 sections, the fifth covering the extent of the Act and its commencement date. Section 1 covers the test to determine if something is obscene; an article is taken to be obscene if the entire article "is, if taken as a whole, such as to tend to deprave and corrupt persons who are likely, having regard to all relevant circumstances, to read, see or hear the matter contained or embodied in it". The test is based on "persons"; "DPP v Whyte" AC 849 established that it was not sufficient for an individual to be depraved or corrupted, it must be that a significant number of people likely to read it would become corrupt. "article" is defined within Section 1 as anything containing material that is read or looked at, any sound recordings and any film or other picture record. A publisher, as used in the Act, is also defined in Section 1; "publisher" is taken to mean anyone who "distributes, circulates, sells, lets on hire, gives, or lends it, or who offers it for sale or for letting on hire", or "in the case of an article containing or embodying matter to be looked at or a record, shows, plays or projects it". The Criminal Justice and Public Order Act 1994 amended this section to include the transmission of the article electronically.
