Mondelez International says the recently introduced cost-focused demands on marketers are already yielding benefits as lower advertising costs and overheads offset lower revenues in its latest quarter. The snacks maker has been prepping senior marketers to make sustainable cost reductions since February.

Yesterday, Coke's Vice President of Innovation David Butler gave a detailed explanation of how the network operates.
