Martha Stewart Living Omnimedia Inc. (MSO) is a diversified media and merchandising company founded by Martha Stewart owned by Sequential Brands Group since December 4, 2015. It is organized into four business segments: Publishing, Internet, Broadcasting media platforms, and Merchandising product lines. MSLOs business holdings include a variety of print publications, television and radio programming, and e-commerce websites. The company was founded, in 1997 by Martha Stewart, as an umbrella for the various media and merchandising ventures linked to the Martha Stewart brand. It went public on the NYSE on October 19, 1999. The stock opened at $18 a share, but shot up to $38 a share, making Stewart an instant billionaire. She served as president, chairwoman and CEO of the company until being forced to resign as a result of the ImClone insider trading case. As part of an agreement with the SEC, she was banned from serving in any role that would allow her to prepare, audit or disclose financial results of a public company until August 2011. In effect, this banned her from serving as an officer of her own company. However, she still owns a 96 percent controlling interest.
