Beth Comstock is comfortable with change. In college, she wanted to be a doctor, but organic chemistry wasn't her strong suit, so she shifted to journalism. When journalism didn't work out, she started working in publicity. So, when GE bought NBC in 1986 right as Beth was starting her career in advertising, she was ready to adapt again. She worked her way to becoming CMO of GE and then, the company's first female Vice Chair of Business Innovations.
