In 1988, a struggling sportswear company introduced this memorable line into its advertising and soon catapulted to the front of the pack. The company is called Nike. A great number of people have heard of it. This quality slogan brims with attitude and captures the defiant and determined mentality that's required of successful sports stars.

"Just Do It" is a bold statement that inspired athletes to work harder. It was and is a no nonsense call to action that audiences instantly associate with Nike's apparel and accessories. It also serves as encouragement to customers when they're looking to buy athletic merchandise.

In 2014, the Nike brand was valued at $19 billion, making it the most valuable brand among sports businesses.
