We'll stop watching new 'Game of Thrones' trailers when they've stopped being badass or we've seen the entire season in trailer form, whichever comes first.
HBO has figured out the best way to advertise: via Game of Thrones trailers. This awesome new trailer for season five was released to help raise awareness about HBO GO availability on PlayStation.
I don't know if HBO realizes exactly how much GoT-based promotional power they have right now, though. They could partner with an adult diaper company and cut together clips of Game of Thrones and incontinent people, and I'd still watch it. Actually, HBO, that would be amazing and weird. Please make that. Thanks.
