- Extreme or hardcore pornography; or, less strictly, any pornographic content.
Pornography—or "porno," to use the hip term—is intended primarily to sexually arouse the viewer, or reader, or maybe listener. Porno films enjoy graphic realism. These are the XXX films.
1973, William Rotsler, Contemporary Erotic Cinema, Penthouse/Ballantine, page 262 more examples
The pornography industry, like all industries, is in the business of making money. Pornography makes a lot of money-from Playboy magazine to XXX videos. This industry would obviously produce, and capitalize upon, pornography for women as well, if a demand existed.

Squash almost without stint! What is squash? Why, squash is squash! Squash in "Poplar" language stood for beer. Not XXX. beer, or Burton beer, but beer for all that. Table beer—school beer—beer of which a great deal might be taken without producing intoxication.
1882, Frederick Sherlock, More Than Conquerors, Home Words Publishing Office, page 79It is wonderful how quickly a beer drinker, if he was to get XXX. beer for XXXX. beer, would be able to tell you the difference. Some publicans go in for more profit than others, some will buy the XXX. beer, and perhaps his next neighbour will buy the XXXX. beer; but the man who sells the XXXX. beer gets the business.

Origin
XXX · symbol, adjective
1969 (see quotations). Reduplication of X (“an age rating denoting content suitable for adults”), in reference to the X rating introduced by the Motion Picture Association of America on 1 November 1968 for films containing extreme violence, heavily implied (originally softcore) sex and obscene language. Film posters began to include multiple exes (but skipping two) in order to imply even more extreme, hardcore content, particularly in relation to pornography (although many actually contained the same content as X-rated films). Compare XXXX. The original X rating was superseded by NC-17 in 1990; see also R-18.
