Answer:
dynamically continuous innovation
Explanation:
Dynamically continuous innovations take place when a new product is launched that changes consumer habits, but that change is not large enough to change the usage patterns of the customers. For example, cable TV changed to satellite TV which represents a technological innovation that didn't change usage patterns.
The change from a regular toothbrush to an electric toothbrush represents an innovation but it will not change how many times you must brush your teeth per day.
