This series was rated as "the greatest series of the 21st century". It was co-created by Jerry Seinfeld and Larry David. It was broadcast on NBC from 1989 to 1998, with a total of 180 episodes. "Seinfeld" is set in New York. The main characters include the comedian "Seinfeld" Seinfeld played by Jerry Seinfeld himself, his long-time friend George (Jason Alexander), his ex-girlfriend Elaine (Julia Louis-Dreyfus) and his next-door neighbor Kramer (Michael Richards). The biggest difference between "Seinfeld" and other sitcoms is that it is "A show about NOTHING", with no theme and no main line. Each episode is self-contained, and the main plot is the daily life, work, heterosexual relationships, etc. of the four main characters, and the jokes are also laid out in it. However, such a sitcom about nothing immediately received unanimous praise and love from critics and audiences after it was broadcast, and the ratings have been high for years. In 2002, the authoritative American television magazine "TV GUIDE" ranked the show first in the "50 Greatest Shows of All Time", and George and Kramer were listed as "TV's Greatest Characters".
