The most notable of his recent screenplays is "30 Rock" (2008), which has received national acclaim and many awards including Emmy awards for Outstanding Comedy Series in 2007, 2008 and 2009. The show was renewed by NBC for a sixth season in 2010. Tina Fey was the original project writer, and created the storyline to be based on her own life story. Sullivan collaborated with three other producers, including Alec Baldwin on this show, especially on the second season. However, despite winning awards for being an outstanding comedy, "30 Rock" has been chronically underrated throughout its six seasons of being on air, with a viewership of nearly 5.3 million viewers.
