The following video is part of our "Motley Fool Conversations" series in which consumer goods editor/analyst Austin Smith and industrials editor/analyst Brendan Byrnes discuss topics across the investing world.

In today's edition, Brendan and Austin discuss the likelihood of a merger between pharmacy titans CVS Caremark (NYSE: CVS) and Walgreen (NYSE: WAG). With the recent fallout between Walgreen and Express Scripts (Nasdaq: ESRX), the industry dynamics are shifting dramatically. Add in the backdrop of Express Scripts and Medco (NYSE: MHS) attempting to merge, and there is speculation that the big pharmacy boxes will also have to consolidate in order to maintain some leverage.
