Earlier quoted context omitted.
What exactly would you call it then, if not a banner ad? It's a large, colorful, rectangular 5:1 panel that advertises a company. Cut the doublespeak.
It's not an ad because it's an organic search result, which is directly relevant to what I'm searching. It's essentially the same as Google Image search result, only better suited for this particular page and request.
