In 1998, Seinfeld went on tour and recorded a comedy special entitled "I'm Telling You for the Last Time". An album of the same name was also released that year, and it featured samples of his stand-up performance.

After his sitcom went off the air, Seinfeld returned to stand-up comedy. The process of developing new material was chronicled in a 2002 documentary, Comedian, directed by Christian Charles. Jerry Seinfeld has written a few books, mostly archives of past routines.

Seinfeld also appeared in two 'webisode'[2] promoting American Express Credit Cards in which he appeared together with an animated rendering of Superman, voiced by Patrick Warburton (who had portrayed David Puddy on Seinfeld). The webisodes were aired in 2004 and directed by famous director Barry Levinson.
