The term "disruptive innovation" refers to technological advancements that significantly alter or replace existing markets and value networks. Such innovations often begin at the lower end of the market and, over time, improve, eventually displacing established competitors. Examples include the rise of digital photography, which disrupted traditional film photography, and the advent of streaming services that challenged conventional television and movie distribution models. Recognizing disruptive innovation is crucial for businesses to adapt and innovate continually, ensuring their long-term relevance and competitive advantage in a rapidly changing landscape.
