Mere-exposure effect: where it comes from

Robert Zajonc showed people unfamiliar words and Chinese characters different numbers of times; the more often they had seen one, the more they liked it (Zajonc, 1968).

In ads it shows up as jingles, mascots and slogans run for years, and campaigns repeated until they feel like part of everyday life.
