Word for today

A new word on the news has attracted my attention. Upskirting. This is the act of photographing up someone's skirt. There has been a bit of it about at the Australian Open with a couple (three?) charged. There was also someone caught in a youth hostel - with a camera poked under a bathroom door. In one case the camera was concealed in a shoe. So is this a new phenomonem? Or just getting more coverage? And is there a reason for Upskirter interest in the tennis?
