Once of the sessions I attended was on how to target digital mums.
WD Pearce (UC Berkeley) had an interesting presentation. His hypothesis was digital is a tool to make her a better mom - it is not digital mom but moms in digital era. There is no separate segmentation as all moms are adapting digital gadgets and mediums faster than any other segmentation. She has 3 hours less everyday due to parenting and technology helps her bridge that gap.
All moms have some digital gadgets and 65% of them use more than 5 technologies to make their lives better.
