In the video above, Vice President of advertising agency, EGC Group, Nicole Larrauri runs through why Wal-Mart is handling the economic bullshit like a champ. One aspect of that is the AC/DC promotion and the brands fast response to the credit crisis.
Warning: As Larrauri moves onto other brands, the video becomes drastically less interesting, but the first 1:48 seconds acts as a fast, skimmed case study.
