Watermarking is a deterrent to the people who upload the content in the first place. The ones who're careless about who they'll share things with. A unique watermark (steganographic or visible) is about finding the source of the leak. In that arms-race the entertainment industry is facing people who can remove a watermark - but we have no idea whether or not they're winning. The fact that torrents exist with watermarks intact makes me think that perhaps they are.
I would have gladly paid them to watch a stream at 8pm last night, yet somehow that still isn't an option in 2015.
Instead I ended up with 4 episodes from a torrent at 8:15. Tell me more about embracing new technology as it comes to market.
HBO Now is Apple TV exclusive for 3 months.
I googled around for about 15 minutes and was only able to find news articles announcing it. I'd be happy to pay them for what i've already watched if anyone could direct me to a sign-up for this elusive streaming service.
I don't have an iOS device or their specific supported ISP, so I haven't signed up.
The visible fingerprint might just have been there to deter the clueless. In any case even with a fingerprint its hard to proof without a doubt, the individual who actually stole it.
I don't think they need to prove that a certain individual stole it. The party which received the advanced copies likely had to take on liability, so HBO can go after them. Of course, that doesn't mean they won't turn around and lean on the actual culprit, but whether or not they catch someone HBO will have their due.
