Let's say there is currently a well-accepted idea. It was developed by person #1, but it was person #2 who popularized it.
For example, Six Sigma has been a hot topic for large corporations for several years. It was conceived at Motorola, but GE was most famous for making ppl realize its benefit.
So, the question is, who should get more credit?
1. The person/entity who conceived the idea; maybe they did a lot of innovative research and experiments to make it possible.
or
2. The person/entity who popularized the idea; they are the one who convinced the world to adopt the idea.
