What were the first words spoken on MTV?

The answer is: Ladies and gentlemen, rock and roll. When launching something with as simple a concept as MTV, it needed its initial message to be short, sweet, and to the point. “Ladies and gentlemen, rock and roll,” as delivered by John Lack, is poetic. Sure, MTV lost its way in the long run, but those early days were the only way most of us got exposed to new music.Source
