The entertainment industry seems to be doing better than ever. Did piracy actually reverse growth at any point in their history?
Today you can buy new-release movies from your PC, smartphone, tablet, set-top box or smart TV and either download or stream them instantly. You can buy combo-packs in store that come with both physical discs you own and a digital download license. The download-only rights for new releases cost substantially less than discs; charging the same was a common complaint of pirates on messages boards for years (e.g. today you can buy Elysium on Amazon at $3.99 to rent, $12.99 for digital purchase, $19.99 for DVD or $27.99 for BR+Download). The digital versions are available as soon as, or even earlier than, the disc versions. Tens of thousands of movies that few would want to purchase are available on a dozen streaming services for less dollars a month than buying a single movie outright.
Almost every objection to legal purchases made by pirates over the years has been answered; the studios gave us what we asked for. Their content is available at reasonable prices virtually wherever and whenever you want it, at least within their own countries (international licensing is still a mess). BitTorrent's share of US internet traffic went from 33% in 2006 to 21% in 2011 to less than 7% in 2013. I don't think that's coincidental.
