To be honest, I've never seen a racquet commercial in TV. Occasionally, I'd youtube an advertisement just for kicks, mostly to see Djokovic mock Sharapova. But I don't know, but I don't think there's much marketing going on in reality. Most of it's you guys rambling on about racquet specs and how "plush" a certain frame is.
Personally, I think it's you guys that do the real marketing.
