Network Effect
Description
The network effect is a concept in economics and business that describes the positive feedback loop that occurs when the value of a product or service increases as more people use it. This phenomenon is also known as network externality or Metcalfe's law, named after Robert Metcalfe, the inventor of Ethernet.
The network effect can be observed in a wide range of products and services, from social media platforms and messaging apps to transportation services and marketplaces. In essence, the more people use a product or service, the more valuable it becomes to its users, and the more difficult it is for competitors to enter the market and replicate its success.
There are two types of network effects: direct and indirect. Direct network effects occur when the value of a product or service increases as more people use it directly, such as with social media platforms, messaging apps, and online marketplaces. Indirect network effects occur when the value of a product or service increases as more complementary products or services are available, such as with gaming consoles and their corresponding games.
