Co-creator Jon Lovett tweeted, confirming the news that "1600 Penn" has been canceled:
"1600 Penn" writer Dan Hernandez replied:
Showrunner and stars Jenna Elfman, Josh Gad and Adam Shapiro also tweeted about "1600 Penn" being canceled:
NBC's decision to cancel "1600 Penn" comes as no surprise.
Starring Bill Pullman and Elfman as the president and his first lady, and "Book of Mormon" alum Gad as the President's hapless son Skip, the White House sitcom premiered to almost 7 million viewers back in December, but continued to fall in the ratings during its first season's 13-episode order.
Rounding out NBC's struggling Thursday night comedy block, "1600 Penn" hit series lows of 1.89 million viewers for its last two episodes that aired in March.
NBC has previously canceled "Animal Practice," "Do No Harm," "Ready For Love" and "Deception." In addition, two long-standing comedies -- "30 Rock" and "The Office" -- ended their run in the 2012-2013 season.
