The Benchmark Series: Memory Decay

In “Advertising Effectiveness: The Long and the Short of it”, Les Binet and Peter Field showed that advertising works in two ways; in the short term to drive sales amongst those already in the market and also in the long term, by creating memories that drive customers to choose one brand over another at a later time.

TV advertising works best in the short term and in the long term

All of us who live in the Marketing world hold our breath when our new campaign goes to air, knowing that the shape of the sales curve could well shape the next career step. So the short term sales impact is important, because it is personal. And we know which video media platform works best to drive an immediate sales spike thanks to the work of Professor Karen Nelson Field from the Centre for Amplified Intelligence. The Benchmark Series showed that in the short term, visibility and attention drive sales irrespective of video platform.

We know that the truly great campaigns drive a strong sales spike initially, but then keep working for the brand in the longer term to raise the baseline. So, for the latest tranche we asked Professor Nelson-Field to re-test how these platforms perform over a longer time period. And what did she find?

Ads watched in a TV content feed, viewed on any screen, not only generated a greater immediate sales impact than ads watched on Youtube or Facebook, but they also continued to generate a greater sales impact long after Facebook and YouTube advertising memories had completely faded. The Professor found that following one execution, TV advertising keeps working to drive a sales impact for 109 days, compared with YouTube at eight days and Facebook at six days.
