As I point out in the presentation, advertising follows the business cycle, but contractions tend to be more severe and pronounced than changes in real GDP because advertising spend can be adjusted quickly. For that reason, advertising is one of the first expense line items to be adjusted in the face of an economic downturn. That reactivity can help a company to preserve precious cash in a deteriorating economy, but it can also steal revenue from the future: more productive is adapting to new consumer spending habits and eliminating unproductive advertising expenditure. The goal of this presentation is to outline some tactics for achieving that.
