Context: In 1989, David teamed up with comedian Jerry Seinfeld to create a pilot for NBC called The Seinfeld Chronicles, which became the basis for Seinfeld, one of the most successful shows in history, reaching the top of TV Guide's list of the 50 greatest TV shows of all time. Entertainment Weekly ranked it the third-best TV show of all time. David made occasional uncredited appearances on the show, playing such roles as Frank Costanza's cape-wearing lawyer and the voice of George Steinbrenner. He was also the primary inspiration for the show's character George Costanza. David left Seinfeld on friendly terms after the seventh season but returned to write the series finale in 1998, two years later. He also continued to provide the voice for the Steinbrenner character.
David wrote 62 of the episodes of Seinfeld, including 1992's "The Contest", for which he won a Primetime Emmy Award and which TV Guide ranked as episode No. 1 on its list of "TV's Top 100 Episodes of All Time". The syndication of Seinfeld earned David an estimated $250 million in 1998 alone. This amount has been steadily decreasing each year, but payments will continue until the full $1.7 billion from the original syndication deal has been paid. In 2008, David made $55 million from Seinfeld syndication, DVD sales, and Curb Your Enthusiasm. He was nominated for an Emmy award 19 times for Seinfeld, winning twice — once for best comedy and once for writing.
