Lay's WOW Chips were fat free potato chips produced by Frito-Lay, containing olestra. They were first introduced in 1998. Although initially popular, charting sales of $400 million in their first year, sales dropped to $200 million by 2000. This was largely due to the possibility of unpleasant side effects (including stomach cramps and diarrhea), warnings of which were required to be included on the packaging. In 2003, the FDA no longer required the warning, as modifications had all but eliminated the risks. Around the same time, the WOW brand was renamed to "Light."
