The Great Recession of 2008–2010 affected the global and U.S. economies and its companies more universally than any economic downturn since the Great Depression. This study explores how the Great Recession influenced the marketing decisions of firms and the resulting long-term effects on marketing within business-to-business companies. Empirical evidence from previous recessions suggests that companies should focus on their customers and increase their marketing efforts during a recession. However, many companies typically slash their marketing budgets during economic downturns. Authors found that during the Great Recession, companies reacted differently than in previous recessions with their marketing responses. Authors conclude their analysis by proposing that the Great Recession will have three long-term effects on marketing in business-to-business companies.
