Well, we all have a go at it at some point.
Latest target in the US Senate seems to be videogames, which no doubt will drag the children of the US down into the moral mire of degeneracy from whence they shall not escape. So Wired has put together this handy little list or morally destablising pasttimes through the ages it refers to as The Culture War.
Thus we have movies demonised:
"This new form of entertainment has gone far to blast maidenhood ... Depraved adults with candies and pennies beguile children with the inevitable result. The Society has prosecuted many for leading girls astray through these picture shows, but GOD alone knows how many are leading dissolute lives begun at the 'moving pictures.'"
- The Annual Report of the New York Society for the Prevention of Cruelty to Children, 1909
And (my favourite), that evil canker eating at the heart of society, the waltz.
"The indecent foreign dance called the Waltz was introduced ... at the English Court on Friday last ... It is quite sufficient to cast one's eyes on the voluptuous intertwining of the limbs, and close compressure of the bodies ... to see that it is far indeed removed from the modest reserve which has hitherto been considered distinctive of English females. So long as this obscene display was confined to prostitutes and adulteresses, we did not think it deserving of notice; but now that it is ... forced on the respectable classes of society by the evil example of their superiors, we feel it a duty to warn every parent against exposing his daughter to so fatal a contagion."
- The Times of London, 1816
