Netflix is really bad for DVD sales, according to new research

Having movies available on Netflix is really bad for DVD sales, according to new academic research.
In 2016, subscription streaming video from the likes of Netflix overtook disc sales for the first time, at $6.2 billion to $5.4 billion. Netflix pays billions to licence TV shows and movies, so the rise of subscription video isn’t inherently a bad thing for the movie industry.
But a new academic study, pointed to by TorrentFreak, suggests that having a movie on Netflix can depress DVD sales in a major way.
