Remember when Madonna was the coolest bitch on the face of the planet? It was some time around 1983 through 1990. During that time Madonna revolutionized the music video and set the bar for the modern pop diva. Through a series of reinventions, Madge inspired and disseminated trends, influenced a generation of women and put out some seriously great music. That's not to say she stopped doing that after 1990, but that was by far her greatest artistic and stylistic period. Of course, being the cultural force she is, Madonna kept going and kept pushing boundaries -- all the while blurring the lines between fashion and music so that today it's unimaginable conceiving one without the other. So while it's great to go googoo over Gaga, here's what made (and still -- when she feels like it) makes Madonna the coolest bitch on the face of the planet.
