There is almost no product differentiation in the industry. The channel through which a product is delivered to the consumer differentiates it by restricting it to specific viewing mediums (computers vs. TVs) as well its degree of sophistication (i.e. resolution, sound quality and encoding, special features). Competitors may also differentiate themselves by deepening their title selection. Needy consumers, who prefer hardcopy video will avoid newer channels, while a greater portion of consumers gravitate toward easy-to-use mediums such as online rentals and VOD services. Hence, product differentiation is minimal and exists only across segments, or between consumer groups. There is relatively uninhibited access to distribution channels. The home video entertainment industry is a conglomeration of distributors and market share is determined by distributional effectiveness, making this factor very important for the threat of entry.
