Just a short time after Oprah announced that she was ending her talk show on network TV to start her own cable channel, Martha Stewart just announced that she too is leaving network TV. Although she does not yet have her own cable channel, the Hallmark Channel is offering her a new home with control over most of the daytime lineup. Stewart said they were in the works of the transition before Oprah made her announcement, but that Oprahs decision reinforced their goal to go cable.
