About the article "Rules of Engagement (TV series)", section "History".

Candidate passages:
The show was heavily promoted by CBS during Super Bowl XLI and launched the following night, the first of seven episodes in its first season.
The pilot episode remains the highest rated episode of the show.
The series was renewed for a second season which began as a midseason replacement for "The New Adventures of Old Christine" on Monday, September 24, 2007, with production halted after nine episodes on November 6, 2007, in the wake of a writers' strike.
After the strike ended, CBS announced that the show would return April 14, 2008, with a further six episodes.
Seasons three and four were both mid-season entries launched in March 2009 and March 2010.
On May 18, 2010, it was announced that CBS had renewed "Rules of Engagement" for a 5th season.
It was later announced that this season would start in September, in contrast to its usual midseason start, and received an expanded 24-episode order.
(The fifth season was the first and only season to have a full-season order.)
The first 15 episodes aired on Monday nights, usually in the 8:30 pm Eastern/7:30 pm Central time slot following "How I Met Your Mother".
Then on February 24, 2011, the series moved to Thursdays at 8:30 pm Eastern/7:30 pm Central, following "The Big Bang Theory", after the cancellation of "$h*!
My Dad Says".
On May 17, 2011, the series was renewed for a sixth season to begin airing in fall 2011.
One day later, CBS announced that "Rules of Engagement" would move to Saturday nights at 8:00 pm Eastern/7:00 pm Central as part of the network's new "Comedytime Saturday" block; the first time in six years that an original CBS program would air on that night.
It also marked the fourth night that the series would air on, with it previously airing on Mondays, Wednesdays (two airings), and Thursdays.
On October 7, 2011, however, it was announced that "Rules of Engagement" would move back to its 8:30PM EST Thursday timeslot following "The Big Bang Theory", replacing new sitcom "How to Be a Gentleman" which was moved to the new Saturday time slot.
Effective January 12, 2012, CBS removed "Rules of Engagement" from its Thursday lineup, replacing it with the new sitcom "Rob" starring Rob Schneider.
"Rules" would return to its Thursday 8:30 PM time slot on March 29, after "Rob" had finished airing its 8-episode order, resulting in a total of 15 episodes in season 6.
On May 21, 2012, CBS renewed "Rules of Engagement" for a seventh season of 13 episodes to air mid-season, bringing the total number of produced episodes to 100.
Season 7 began airing on Mondays at 8:30, starting February 4, 2013.
On May 10, 2013, "Rules of Engagement" was cancelled by CBS after seven seasons and 100 episodes.
The series finale episode aired on May 20, 2013.
