'Piracy' is such an ugly word. Even in its most fun, swashbuckling sense, it's got the ring of plank-walking and scurvy to it. Now it seems like even less of a laugh, what with Captain Phillips and the other, much less violent piracy of TV and film on the internet suddenly coming under much more scrutiny.

You probably don't look at it this way, but using your mate's/partner's/parents'/flatmate's partner's parents' Netflix account is sort of piracy, and according to a new study it's a practice that's costing the streaming service $192 million a month.

The study by Cordcutting.com says that Netflix is the service which users sponge off other people for the longest, with an average span of 26 months. That's compared to 16 months for Amazon Prime and 11 months for Hulu. It's mostly kids using their parents' log-in details - a solid 48% of all Netflix stealers - as well as some 14% using their siblings' accounts.

However, it's not all the millennials' fault for once. The study says that while millennials are the most likely demographic to be pirating Netflix - 18.1% of those who use the service are on another person's account, compared to 10.9% of baby boomers and 8.9% of Generation Xers - the boomers are the biggest group pirating Amazon Prime. Nearly 20% of boomers on Prime are pirating it, compared to 17.7% of millennials and 12.7% of Gen Xers.

If this proves nothing else, it's that all those "yOu woULdN't SteAL a HAndbAG" trailers at the start of every single DVD and video released from 2004 onwards freaked the Gen Xers far, far more than anyone else.
