Disruptive innovation can have a significant impact on established businesses and their competitive advantage. Disruptive innovation often involves introducing new products or services that are significantly different from existing offerings. This can lead to disruption of the existing market, as well as a shift in the competitive landscape. Established businesses may find it difficult to compete with the new offerings, as they may lack the resources or expertise to keep up with the new technology. Additionally, established businesses may struggle to maintain their competitive advantage in the face of disruptive innovation.
