The series was aired uncut on subsequent channels following its cancellation by Disney Channel.
Both Channel 5 and 5* aired the series in its originally-produced widescreen format.
The series was shown on both these channels full uncut, despite the fact it was shown pre-watershed (9.00 pm), although, the show was issued an age rating.
On RTÉ Two it was issued a 'PS' rating and on TG4, a '12' rating.
After Ritter's death, it had slipped to 50th, but was renewed for a third season, in which ABC moved the series to Friday at pm as part of its TGIF comedy line-up.
The series' creator and showrunner, Tracy Gamble, left the series for a time over creative differences prior to the third season, but he later returned as a consulting producer midway through the third season. Even before the third-season finale's airing, rumors began circulating that 8 Simple Rules was facing cancellation due to Ritter's death and poor ratings.
The series's name and premise were derived from the book 8 Simple Rules for Dating My Teenage Daughter by W. While 8 Simple Rules was renewed for a second season and production had begun, Ritter's sudden death in September 2003 left the series in an uncertain position.
After a hiatus, the series returned and continued without Ritter, with the producers deciding to kill off Paul and not replace him.
On October 3, 2009, 8 Simple Rules returned to ABC Family, having been absent for a year, airing on Saturdays from am to am, and Sundays at a.m.- pm Airings have been sporadic due to the channel's unpredictable movie schedule and holiday programming block.
It was picked up by ABC1 which aired the show until the channel's closure in 2007.
The same year, Channel 5 began airing the series, in which season one only aired, then from 2008, was shown on 5*, which aired all three seasons.
While 8 Simple Rules ratings were well above those of the surrounding TGIF shows during its third season, ABC cancelled it due to the perceived inability to sell reruns of the show into syndication (a fourth season would have given the show the 100 episodes necessary to enter daily syndication).
On July 11, 2005 (less than two months after ABC officially cancelled it), The WB network announced it would air back-to-back repeats of all 76 episodes of 8 Simple Rules from 4–5 p.m.
The finale received a 3.9/8 rating share which gave ABC a third-place finish behind NBC's Dateline (5.8/11) and CBS's Joan of Arcadia (4.9/10), which starred Ritter's son, Jason.
