“Netflix has what some people fashionably call a “long tail” business. Its catalogue of more than 45,000 titles means that it can cater to almost any interest. Such a depth of movie offerings, plus online features such as movie reviews and recommendations, increases its popularity. Unlike a typical high street video-rental store, which might get the bulk of its revenue from just a few hundred recent titles, Netflix’s revenue comes from a far broader selection: some 35,000 different film titles are contained in the 1m DVDs it sends out every day.”
