MediaLink's Wenda Harris Millard has it right. More CMOs are needed in corporate board positions. 

CMOs today are the growth engine and strategic leaders who are versed in board level topics ranging from reputation management to digital transformation to innovation and designing the customer experience. They manage strategy, technology, risk and compliance and have the right skill to lead at the highest level. 

With so few marketing leaders on boards today there is lots of room for the CMO to expand their influence in this area.
