Network economies of scale occur when a product or service becomes increasingly valuable as more people use it. Unlike traditional supply-side economies that lower production costs, these are demand-side forces that dominate the digital age. Think of a telephone or social media app: a single user has zero utility, but a massive user base creates immense value. This dynamic triggers a powerful winner-takes-all market. Once a platform gains momentum, a virtuous cycle attracts everyone, establishing insurmountable barriers to entry. Ultimately, network effects explain why tech giants maintain absolute monopolies. Rivals cannot survive simply by offering better software without active users.
