When Brands Go Dark, Extending the Evidence
This research replicates a 2021 study by Nicole Hartnett and colleagues who had analyzed what happens to sales when brands stop advertising for a year or longer. The difference in this new work is not only its focus on the impact of going dark on market share, but its use of much more extensive data, with farther-reaching conclusions and future research recommendations. It adds robustness to the prior evidence that when brands stop advertising, declines become more common and more significant, on average, as time increases.
