Changes

Pornography has often been subject to [[censorship]] and legal restraints to publication on grounds of [[obscenity]]. Such grounds and even the [[definition]] of pornography have differed in various historical, [[cultural]], and national [[contexts]]. With the emergence of [[social]] [[attitudes]] more [[tolerant]] of [[sexuality]] and more specific legal definitions of obscenity, an [[industry]] for the production and [[consumption]] of pornography arose in the latter half of the 20th century. The introduction of home video and the [[Internet]] saw booms in a worldwide porn industry that generates billions of dollars annually.
