The last time that Americans and their government got their knickers in a twist over supposedly “obscene” content on television, the result of the brouhaha was the much-heralded V-Chip, which was mandated for all new TV sets, and which provided concerned parents with a way to prevent their children from viewing inappropriate programming, even when unsupervised. But, in what could be seen as a measure of just how much ordinary Americans actually care about this issue, it turns out that virtually no one uses their V-chip, and many parents don’t even know (or care) how to turn it on. So the government has launched a new ad campaign to tell viewers all about it.
