PART B_2

In the second type of network externality, the number of users decides indirectly how valuable a product or a service is. For instance, the Windows operating system has more users than Mac OS. Because of that, the number of people who use Windows as their software increases. It has also become the market leader for many years now. Another example of this is the competition between VHS and Betamax. Both are the video cassette formats from the 1970s to 1980s wherein both were introduced at the same time. Betamax offered better picture quality. However, the manufacturers of VHS were able to convince other companies to promote their products fast. Moreover, it provided a wider range of rental movies and a good quality for average consumers. As a result, more and more people prefer to use VHS which made Betamax eventually disappear.

The network effect usually leads to another effect which is a certain standard. This standard becomes widely used and often dominate the market. This effect is called the de facto standard. Products that meet the de facto standard usually end up having a larger share of the market. This made many companies adjust to the de facto standards. Meanwhile, consumers must be careful about this phenomenon. So, it is important to know their priority between the popularity and the quality of the product.
