People with big job titles–especially in marketing–are starting to notice. Twitter CMO Leslie Berland tweeted, “Hey @CES. Big respect for what you’ve built. Please do better here. I’ve got a long list of amazing women to hit your stage. Let’s talk. #changetheratio.” HP’s global CMO Antonio Lucio jumped on that thread and took it to 11. “All men should boycott @CES if women are not invited to speak!” he wrote. Others calling out CES include former PepsiCo Global president Brad Jakeman, Twitter director of sales Robin Wheeler, and ToysRUs global CMO Carla Hassan.
