The Long Tail theory is when a company focuses on the large mainstream products, rather than using products from small niche markets. An example of this is films. On large international websites, when someone shows interest in a large film, they can show recommendations of other large blockbuster films. However, websites like amazon and play.com, choose products fit for the consumer's tastes and interests, for example, if they happen to be a huge horror film fan, the website will recommend other horror films.
When selecting Halloween, the films which were recommended, due to past consumer choice, was Cabin Fever, Orphan etc, mainly from the horror genre, but most notably, the subgenre 'slasher'.
