The ten rules of dating effect dating to students
The third season finale was not aired for May sweeps.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.
Kaley Cuoco, Amy Davidson and Martin Spanjers co-starred as their teenage kids; Bridget, Kerry and Rory Hennessy.
Shortly afterwards, ABC officially cancelled 8 Simple Rules in May 2005.
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).
James Garner and David Spade later joined the main cast as Cate's father and nephew, Jim Egan and C. Barnes, in an attempt to fill the void left by Ritter.
After three seasons, ABC cancelled 8 Simple Rules in May 2005 due to low ratings.
