Marketers and businesses have been courting a new breed of do-it-all moms. These "alpha moms" are the leaders of the pack, keeping up on the newest products and trends and passing the word on to their mommy peers. "Alpha moms are incredibly influential," says Isabel Kallman, CEO of Alpha Mom TV, a new cable TV channel that targets moms. She says if alpha moms believe in a new product, they'll become advocates in promoting it by word-of-mouth. That's why Nintendo tested out the Wii on alpha-mom focus groups months before its release.
