Definition: The term 'Progressively Simplify Distinctive Niche Markets' is a term that describes a strategy used by businesses to expand their market reach and customer base without significantly expanding the product or service offered. This means that instead of introducing a new feature, technology or a change in price, they simplify existing features, products or services so that customers can easily switch from one platform or application to another.

One example sentence using this term could be: "Our company is constantly upgrading our products and services to meet the evolving needs of our diverse market. We're not just focusing on simplifying the most basic functionalities; we're also ensuring that every customer has a seamless experience, even when they switch from one platform to another."
