Monica Crowley plagiarized PhD thesis. Where was her advisor?

I wonder how technology contributes to plagiarism. On the one hand, you can find (and lift) anything on the Internet these days; on the other hand, it’s a lot easier now to find plagiarized content, and a lot more media consumers will hear about the transgressions.
Was there more or less plagiarism before the Internet age? I doubt that human nature has changed that much…
