A snippet from the BBC's website

From an essay, "Sex, Drugs, and Music Hall," by Matthew Sweet:



"For the first time, pornography was produced in a volume capable of satisfying a mass readership. Oddly, the industry was founded by a gang of political radicals who used sales of erotica to subsidise their campaigning and pamphleteering: when, in the 1840s, the widely-anticipated British revolution failed to materialise, these booksellers and printers found that their former sideline had become too profitable to relinquish. Lubricious stories such as Lady Pokingham, or, They All Do it (1881), and hardcore daguerreotypes, photographs and magic lantern slides, demonstrate the omnivorous nature of Victorian sexuality. Don't imagine that this material comprised tame pictures of gartered ladies standing in front of cheese plants; any permutation or peccadillo you can conceive is represented in the work that has survived from the period. And it was produced in huge quantities: in 1874, the Pimlico studio of Henry Hayler, one of the most prominent producers of such material was loaded up with 130,248 obscene photographs and five thousand magic lantern slides - which gives some idea of the extent of its appeal."
