They have banners, search ads, content ads, and native advertising. Some of their inventory is served by bing, so if you use both bing adcenter and yahoo/gemini, you may be competing against yourself.

But I just launched a yahoo/gemini campaign 2 weeks ago, for leadgen on web. They definitely have more than banners.

(Also, I've found banner ads can refer to either the format [728x90 graphic] or the model [pay per view/CPM/CPV]. They offer the gamut just like everyone else, even the small shady players.

To say that yahoo just has banners is very incorrect.

Plus Yahoo! bought Flurry recently, which gave them additional mobile ad units.
