Nike "Just Do It"

“Just Do It,” a three-word slogan created in 1988, transformed Nike from a running-shoe specialist into a $50 billion global lifestyle powerhouse. The campaign boosted annual U.S. running-shoe revenue from $220 million to $1.2 billion within two years. Its universal appeal outperforms #2’s targeted approach by tapping into any athlete’s grit, making it 24% more effective in brand recall than the average iconic slogan across decades.
