Stewart, founder of Martha Stewart Living Omnimedia, served a relatively light sentence of five months of prison, followed by six months of house arrest, for lying during an insider trading probe of a stock sale she made in late 2001.

Stewart was convicted in 2004 on charges of conspiracy, obstruction of justice and making false statements about her sale of nearly 4,000 shares of ImClone Systems stock. The scandal forced Stewart to step down as CEO of Martha Stewart Living and as a director of the New York Stock Exchange.

In August 2006, Stewart agreed to pay a $195,000 fine and to a five-year ban on directing a public company. Her legal woes, however, haven’t kept her down for long: Fortune named Stewart as one of the 50 most powerful women in 2006.
