Retrovation 

Retro-innovation. Innovation that happens when people resist change or when they go back to a state before the change was brought in. Remember, standard definitions of innovation is built around change and consider resistance to change anti-innovative.

People are increasingly going back to the good old days. Retrovation is evident in many new products that we use. Organic, fertilizer free farming is popular again. At the very least, we apply retro-filters on our digital images when we cannot get back to the real bygones. Retrovert has actually become a personality type, just like introvert and extrovert.
