Martha Helen Stewart is an American retail businesswoman, writer, and television personality. As founder of Martha Stewart Living Omnimedia, she gained success through a variety of business ventures, encompassing publishing, broadcasting, merchandising and e-commerce. She has written numerous bestselling books, is the publisher of Martha Stewart Living magazine and hosted two syndicated television programs: Martha Stewart Living, which ran from 1993 to 2004, and Martha, which ran from 2005 to 2012. In 2004, Stewart was convicted of felony charges related to the ImClone stock trading case; she served five months in federal prison and was released in March 2005. There was speculation that the incident would effectively end her media empire, but in 2005 Stewart began a comeback campaign and her company returned to profitability in 2006. Stewart rejoined the board of directors of Martha Stewart Living Omnimedia in 2011 and became chairwoman of her namesake company again in 2012.
