She had PepsiCo (NYSE: PEP) right where she wanted it, too, as a spokesperson for the would-be-edgy soda company in 1989. Pepsi and Madonna produced a very long and affecting commercial using her "Like a Prayer" song, in which Madonna watches the eight-year-old version of herself in a video dreaming of being a pop star one day.
