Ubisoft: Wii is a “Girl-Driven” System
Ann Hamilton, a senior brand manager with Ubisoft, said that Nintendo’s Wii console is a “girl-driven system,” and is one of the main reasons the Wii has had such success in the marketplace.
“What’s driving the Wii sales is the use of Wii by women, girls and families,” Hamilton said in an article from the Tulsa World. “It’s a really female-driven platform.”
It's an interesting read. I wouldn't say that the system is driven by girls, but it's the most unisex a console has ever been.
