Widely regarded as one of the greatest American sitcoms of all time, Seinfeld was created by the comedians Larry David and Jerry Seinfeld. Seinfeld was also the show's eponymous lead, playing a fictionalised version of himself for all nine seasons. Seinfeld ran on NBC between 1989 and 1998. Despite ending over two decades ago, its popularity has yet to wane. In 2021, in fact, Netflix spent over $500 million (£367.3m) for the show's streaming rights.
