Writing a BBC story on big data in market research

I'm writing for the BBC on how cheap access to massive data crunching via cloud services has allowed market research to explore new territories. Assessing facial expressions and reading into the intonation of voice is now possible. But this takes up a lot of processing power and only the cloud can provide that at a realistic cost.

I'm looking for market research pioneers who have harnessed the potential of big data to learn new things about human behaviour. I want to show how they have opened their clients' eyes to customer viewpoints they never previously understood.

Please note, this is not a piece about technology products or a platform for tech industry opinions about future trends.

I only want to talk to people in market research who can flag up real, tangible examples of their achievements using this technology and exploiting the economics of the cloud.

I need to find individuals in marketing and advertising who can explain what the advent of online big data analysis has done for the quality of their customer insights. 

This story is now up on the BBC website, complete with insights into the link between Boris Johnson and Meghan Markle plus why you really loved that rom-com you claimed you snoozed through.
