I’m thrilled to inaugurate the Nielsen News Center with some thoughts on themes I’ve been discussing at various events lately. I believe these themes will define the next 30 years, both for us and for our clients: population shifts; the rise of the middle class; media and retail fragmentation; how advances in measurement will trim waste and drive a golden age of marketing; privacy and security in the age of big data—and why I’d like to be 32 again!
