Here’s a shocker: Forbes and MSNBC are reporting that in a recent survey of 3,500 U.S. mothers by BSM Media, 65% of moms feel that they are “under-served” by advertisers — either because mom-focused ads don’t resonate with them or because the ads aren’t aimed at moms at all. What media works best? Radio works because moms spend a lot of time in the car and online—71% use the Internet to research purchases. On the Web, it’s not necessary about banner ads—-moms want to engage in a conversation. A good deal of action happens at social networks like Maya’s Mom and Café Mom, and at mom-centric blogs like BlogHer.
