Discussion:
If Internet banners were not "invented" could sonebody patent the banner concept?

Answer:
I understand what you have answered. My question was in the hypothetical case that nobody had yet "invented" the banner concept, could somwebody patent it or would it be simply considered an aplication of an Internet link, which is basically what it is?
