Amazon
When typing in 'horror' in to Amazon, under the category 'Shop Instant Video Movie', quite a lot of horror films came up. I sorted them in to the popularity category and this is what came up.
This is the top eight films of the horror genre in Amazon. As you can see the most popular film is a Virus one and that is World War Z. This is because, the film had been recently released. On the list the Twilight saga appears twice. It is at number four and at number seven. This just shows how popular those films are, because they have decided to carry on with the rest of the saga. You can also see quite clearly one of the production companies that made one of the films. That company is Hammer and they made 'The Quiet Ones'. You can look more at hammer if you look at the Production Company Research, under the Audience Research page.
