"Yesterday you said tomorrow", "there is no finish line" and "my sport is your sport's punishment" are Nike slogans used by the company throughout the years. "Just Do It" remains Nike's most well-known slogan since it was first used in 1988.
The slogan, "Just Do It," was proposed by the advertising agency of Wieden+Kennedy and was based off the last words of Gary Gilmore. Gilmore was a killer who was executed in Utah in 1977; he uttered "Let's do it" before he was shot. As of 2015, the "Just Do It" slogan has been used in various Nike advertisements and merchandise.
