On July 5, 1989, "Seinfeld" made an unremarkable debut on NBC and puttered along for a few low-rated seasons before blossoming into a true cultural phenomenon. Now, 30 years later, the misadventures of Jerry, George, Elaine and Kramer stand as one of the greatest and most popular comedies in TV history.
