In fact, Stewart said it's Macy's that didn't uphold its end of the agreement to try to maximize the potential of her business. She said her brand, which is a $300 million business at Macy's, has grown "static" at the department store chain.
"We were disappointed," testified Stewart, 71. "We did have hopes that the business would be much bigger. ... We got to a certain dollar amount and struggled and never got any further."
The trial, which began Feb. 20, focuses on whether Macy's has the exclusive right to sell Martha Stewart-branded products such as cookware, bedding and bath items.
Penney signed a pact in December 2011 with Martha Stewart Living to open shops at most of its 1,100 stores by this spring and buy a stake in Stewart's company. But one month later, Macy's renewed its long-standing exclusive deal until 2018 and sued Martha Stewart Living and Penney.
Martha Stewart Living and Penney are using what they believe is a loophole in the Macy's agreement to move forward with the deal. It's a provision that allows Martha Stewart Living to sell goods in categories such as bedding in Martha Stewart stores.
According to Martha Stewart Living lawyers, because the Macy's agreement doesn't specify that these Martha Stewart stores have to be "stand alone" stores, the mini shops within Penney stores do not fall under the exclusive agreement. Moreover, Stewart said in court Tuesday that even Amazon.com could be considered a store, given that shoppers are shifting more to online buying.
The trial has unveiled some of the drama that has taken place behind-the-scenes between Stewart and the CEOs of Macy's Inc. and J.C. Penney Co.
During his testimony on Friday, Penney CEO Ron Johnson rejected claims by Macy's lawyers that he plotted to push Martha Stewart to breach her deal with Macy's with the goal of eventually becoming the sole carrier of some of Stewart's products.
Macy's attorneys have portrayed Stewart as someone who turned her back on a good friend, Macy's CEO Terry Lundgren, to broker a deal with a rival company. During testimony earlier in the trial, Lundgren said that he hung up on Stewart after she told him about the deal she'd reached with Penney, and hasn't spoken to her since.
Stewart's testimony comes as the company she founded continues to struggle. Martha Stewart Living just finished its fifth straight year of losses. The company has also had steep sales declines.
Martha Stewart Living has been trying to bolster its merchandising business, which represents 30 percent of the company's annual revenue, to offset declines in its broadcast and publishing divisions as people continue to shift toward the Web and mobile apps to get their recipes and food tips.
