Seinfeld was one of the most decade defining sitcoms of the 1990s and its popularity and influence hasn't seemed to waver since it ended. The show was popular, in fact, that its practically impossible to hear the names of its main cast members and not immediately think of their role on it. It's been alleged over the years, however, that the show's popularity is exactly what has prevented them from finding that same level of success in other projects. This infamous theory has been long-known to the public as simply the "Seinfeld curse".
