NATIONWIDE -- Walmart's signature "Smiley" face will again be used in its advertisements after a 10-year hiatus and lengthy court battle.

The classic yellow Smiley face was used by Walmart from 1990 to 2006 until the store became involved in a trademark legal battle with the president of the Smiley Company based in Brussels, Belgium.

The two sides reportedly reached a settlement although its details have not been released.
