A Key Media Difference Between Martha And Oprah Is Their Magazines

Both Martha Stewart and Oprah Winfrey are billionaire owners of media companies (Stewart's Martha Stewart Living Omnimedia is publicly held) who are switching from "free" tv to cable. (Stewart's September 2010 move from largely NBC Universal affiliates to the Hallmark Channel was announced last month; Winfrey's ending her program on its September 2011 25th anniversary was announced last fall with the establishment of the Oprah Winfrey Network.) And they have magazines, but Martha Stewart Living 's 1990 launch came a year before Martha became "omnimedia" with her tv show. O 's 2000 launch came well after Oprah became must-see tv. Both monthlies will celebrate anniversaries in 2010: MSL 's 20th and O 's 10th.
