In 1988, Nike was losing ground to Reebok, particularly in the booming aerobics market. A decade later, its worldwide sales had grown from around $877 million to $9.2 billion, and its US athletic shoe market share had more than doubled.
“Just Do It” is widely credited as the campaign that turned that around. It’s still one of the most recognisable taglines in advertising, and unlike many campaigns of its era, it has barely changed in over 35 years.
This case study looks at what the campaign did, the real numbers behind Nike’s growth, and what UK SMEs can take from a brand built on three words.

What Was Nike’s “Just Do It” Campaign?
“Just Do It” is an advertising campaign and tagline Nike launched in 1988, created by agency Wieden+Kennedy. It used the simple three-word slogan alongside images of athletes, professional and everyday, to build an emotional, motivational message around getting active.
The phrase itself has an unusual origin. Wieden+Kennedy founder Dan Wieden has said the line was inspired by the reported last words of a condemned man before his execution in 1977, adapted from “Let’s do it” to “Just Do It.”
Why Did Nike Launch the Campaign in 1988?
Nike launched the campaign because Reebok had overtaken it in parts of the athletic footwear market, especially aerobics, and Nike needed a way to reach a broader audience beyond serious athletes. Its previous positioning felt narrow in a market that was shifting toward participation over competition.
The first commercial featured an 80-year-old runner named Walt Stack, not a professional athlete, signalling early on that the campaign’s message was for anyone with a body, not just elite competitors.
What Made the Campaign So Effective?
The campaign’s strength was its simplicity: a short, universal message that worked across sports, cultures, and decades without needing to change. It made no claims about cushioning, materials, or technology.
Instead, it associated Nike with motivation and personal achievement, a message broad enough to include a professional athlete and a first-time jogger in the same idea. That breadth is a large part of why the slogan has needed almost no updating since 1988.
What Results Followed the Campaign?
Nike’s worldwide sales rose from around $877 million in 1988 to $9.2 billion by 1998, while its share of the US athletic shoe market grew from 18% to 43% over the same decade. By 2021, Nike’s annual revenue had reached $44.5 billion.
Brand valuation firm Brand Finance ranked Nike the world’s most valuable apparel brand at $32.4 billion in its 2019 report, a position it has held consistently in the years since. Multiple factors drove this growth over three decades, including product innovation and athlete partnerships, but “Just Do It” provided the consistent thread running through all of it.
How Did Nike Use Athletes to Build the Campaign?
Nike built on the campaign through long-term athlete partnerships rather than treating it as a single advertising burst. Michael Jordan became one of Nike’s most significant partnerships from 1985 onward through the Air Jordan line, helping cement the brand’s connection to basketball culture. Bo Jackson starred in Nike’s “Bo Knows” cross-training adverts from 1989, and Serena Williams has been a Nike athlete since signing with the brand in December 2003.
What Happened When Nike Featured Colin Kaepernick in 2018?
Nike featured former NFL quarterback Colin Kaepernick in a 30th-anniversary “Just Do It” advert in 2018, which sparked significant public debate, including some customers publicly destroying Nike products in protest. Despite the backlash, analysis firm Edison Trends found Nike’s online sales grew 31% over the following Labor Day weekend, compared with 17% growth over the same period the year before.
The episode illustrated something specific to Nike’s brand: a willingness to take a clear position, consistent with the “Just Do It” message of individual conviction, even when it was commercially risky.
What Can UK SMEs Learn From “Just Do It”?
The clearest lesson is that a simple, consistent message can outlast individual products, trends, and even controversies, provided it genuinely reflects what the brand stands for. Nike didn’t need to reinvent its tagline for each new product or decade.
I’ve seen smaller businesses fall into the trap of refreshing their core message every time they run a new promotion. In my experience advising businesses in the facilities management and property sectors, the ones that picked a consistent message and stuck with it built recognition faster than those chasing a new angle every quarter.
A practical checklist for applying the lesson:
- Choose a message broad enough to grow with the business, not tied to one product
- Resist changing your core message every time you launch a new campaign
- Use real customers or a relatable figure, not only aspirational imagery, to widen appeal
- Decide what your brand is willing to stand for, and be consistent about it
- Give a message years, not weeks, to build recognition

Frequently Asked Questions
Who created the “Just Do It” slogan?
The slogan was created in 1988 by advertising agency Wieden+Kennedy, founded by Dan Wieden. Wieden has said the phrase was adapted from the reported last words of a condemned murderer, changed from “Let’s do it” to “Just Do It” for the campaign.
Did the “Just Do It” campaign alone drive Nike’s growth?
No single campaign explains three decades of growth on its own. Nike’s revenue rise from $877 million in 1988 to $9.2 billion in 1998, and to $44.5 billion by 2021, reflects product innovation and athlete partnerships too. “Just Do It” provided the consistent message running through all of it.
Why has Nike never really changed the “Just Do It” slogan?
The slogan was designed to be broad enough to apply to any sport, athlete, or decade, which is precisely why Nike has had little reason to replace it. Occasional variations exist, but the core three words have remained Nike’s advertising anchor since 1988.
What happened after Nike’s 2018 Colin Kaepernick advert?
The advert prompted public backlash, including boycott calls and people destroying Nike products on social media. Despite this, analysis of online sales found a 31% increase over the following Labor Day weekend, compared with 17% growth in the same period the previous year.
Can a small UK business use the same approach as Nike?
Yes, in principle. The core lesson, a simple message broad enough to grow with the business and consistent enough to build recognition over years, doesn’t require Nike’s budget. What it requires is the discipline not to change the message every time the business launches something new.
Ready to Build a Message Your Customers Won’t Forget?
Nike didn’t win by changing its message every year. It won by choosing one message and giving it decades to work.
