Martha Stewart learned the importance of branding early on. She used her namesake not only to create a homebuilding media empire but to become the first female self-made billionaire in the United States, at least on paper.
"I had a friend called Charlotte Beers who was a brander, and she kept saying, 'Martha, you're a brand. You're a brand.' And then one day I woke up and said, 'Ah, I'm a brand,' " Stewart told CNBC in a 2014 interview.
