Each week on the M&W Podcast, we discuss Madison & Wall’s latest research and explore how and why money flows through the advertising economy.

This week that new work includes new analyses of earnings results from ad-supported companies including Google and Amazon, Publicis and Omnicom, Canada's Bell Media and many, many more.

In addition, our Advertising 101 series continues with a focus on B2B marketing to explore how it differs from consumer-focused marketing with Ari Osur, formerly a CMO and senior marketers for multiple B2B businesses.

This follows on part 1 with Gerry D'Angelo where we discussed how marketers organize themselves, part 2 with Francisco Escobar on the role of marketing procurement, part 3 with Deborah Wahl on the resource allocation choices marketers make and part 4 with Gordon Ho on the different ways small, medium-sized and large businesses engage in marketing (which you can listen to on episodes 17, 18, 19 and 20 of The M&W podcast).
