In early January 2010, NBC initially announced they were going to renew Law & Order a 21st season, then on May 14, 2010 NBC announced that Law & Order has been canceled after twenty seasons since they have the same thing as a western drama series called Gunsmoke, the longest-running prime-time drama series.
The late announcement of the cancellation resulted in Law & Order not having a "series finale" episode. Had the series continued, it would have been the last to feature S. Epatha Merkerson, who prior to the cancellation announcement had herself announced that she would not return for the 21st season, but Merkerson joins the Chicago franchise series Chicago Med in 2015.
