In 1991 Pat Cadigan expanded the definition of Pornography to include ANYTHING that gets you off in the media...this is her nearly Post Cyberpunk novel Synners. Images of things being blown up, natural calamites, etc. etc. were classified under the heading DISASTER PORN. Shows like Maximum Exposure pretty much cover that territory. There's also Slapstic Porn...Amerika's phunniest home videos being the primary outlet for that.
Pornography is anything that get's you "Off" which may or may not be a graffic sexual depiction. Shows like 20/20 and that show with Stone Phillips on NBC fall under the heading of Scandal Porn.
FOX News and CNN Headline News definitly fall under the headings of NEWS PORN.

Pornography does not necissarily equal erotica.
