As reported on Yahoo! News, McDonald's Appeals to Mothers With Web Promotion. It's basically an e-mail marketing campaign run through a newsletter that aims to draw more mothers into the restaurants with coupons, parenting advice, and health and nutritional information.
Well, personally I would rather focus on targeting teens directly. As a mother I would never suggest my children to eat at McD, they will just go there with friends because a "cool" teen experience.
Anyway, a suggestion... eat pasta, it's much healthier!
